Thermoregulatory instability – Neck pain and inability to maintain consistent body temperature
Ross Hauser, MD
At our center, we see many people with many conditions and symptoms of a neurologic-like nature. The common link that we see in our patients is the link of craniocervical instability and cervical spine degenerative disease and instability. If you are reading this article it is likely that you have some type of neck pain and a long list of medical conditions. One of these conditions may be the inability to regulate your body temperature.

For some thermoregulatory dysfunction started after cervical fusion surgery. For others, it was after a neck injury.
Many people have very successful cervical fusions. Some people however may develop complications. Some of these complications are challenging and difficult to understand. In this article, I hope to help with understanding the possible reasons you suffer from inability to maintain consistent body temperature and other conditions. These causes can be continued post-surgical craniocervical instability and non-surgical related cervical spine instability. For those of you who have not had a neck fusion, I hope to show that cervical neck ligament damage from injury can be a cause.
It started after a cervical fusion.
This is the type of story we hear:
I have had multiple cervical fusions and a cervical disc replacement. I am now experiencing a lot of symptoms. They come and go and vary in their intensity: Headaches, nausea, extreme fatigue, irregular heartbeat, lightheadedness, hand tremors, trouble swallowing, itchy spots on the left side some, right side mostly, trouble regulating body temperature, cracking in the neck when turning.
What can we do for a patient like this? If they are a good candidate for treatment, focus on the cervical spine and neck instability. This is explained below with links to supportive articles and research on this website.
Thermoregulatory dysfunction – this person’s thermostat is broken
The above story tells us of someone who is suffering from many symptoms. In treating the cervical spine we may find a way to treat all the symptoms at once as opposed to picking out the conditions individually and addressing symptom suppression. But we need some science and research to help guide your understanding of how this may be achieved in some patients.
A 2018 paper published in Handbook of Clinical Neurology (1) from the Department of Neurology, University of Maryland School of Medicine sought to help fellow neurosurgeons understand a phenomenon of thermoregulatory dysfunction in people who had just or recently suffered from an ischemic stroke, hemorrhagic stroke, and/or traumatic brain injury. Thermoregulatory dysfunction is a problem that its name well describes. The person who has it cannot maintain proper body core temperature. For some people when they are exposed to the cold, their body gets very cold. When they are exposed to heat, they can get very hot, or conversely, get cold. Sometimes the person gets hot or cold without an apparent external stimulating factor. In simplest terms, this person’s thermostat is broken.
What causes this?
In the world of the neurologist dealing with an immediate health crisis of injury or stroke: “Temperature instability following brain injury likely involves hypothalamic injury, pathologic changes in cerebral blood flow, metabolic derangement (chemical imbalance), and a neurogenic inflammatory response (nerve inflammation).”
Let’s get an important point across now. Many people run a very high fever soon after their stroke or injury event, these problems need immediate medical care. The people we see and for whom this article is intended are the people who suffer symptoms such as temperature instability on a chronic basis with varying degrees of severity.
In the world of a cervical spine specialist who deals with people with chronic, years ongoing neurologic type symptoms that may reveal themselves as temperature instability, we have to look at chronic hypothalamic mis-messaging, pathologic changes in cerebral blood flow (the patient does not get enough blood to the brain), metabolic derangement (chemical imbalance often brought on by prolonged opioid use), and a neurogenic inflammatory response (nerve inflammation – something, like a disc or vertebrae is pinching the nerve).
Chronic thermoregulatory instability and herniated cervical discs
In this article, we are focusing on the patient who has thermoregulatory instability, a problem with fluctuating body temperatures as a chronic condition, and as a symptom among many symptoms that may lead to a diagnosis of cervical spine instability causing.
Let’s go back to the above paper. In an acute injury or stroke, the doctors point out three main regulatory symptoms that can be impacted.
- Cerebral blood flow,
- metabolic derangement (chemical imbalance),
- and a neurogenic inflammatory response.
These are also symptoms that can be very characteristic in patients that have suffered from long term-cervical spine instability. Let’s briefly go through each system, but before we do, let’s put another face to this problem.
C5-C6 cervical disc herniation failed surgery and the symptoms and conditions that include fluctuating temperatures
This is another type of story we hear when someone contacts us for the first time. While this person has had a very unique medical journey, their story as you are probably seeing by now has a familiar tone to it. It may be your story. If you are reading this article because you suffer from temperature fluctuations and a skin temperature that wildly ranges from one side of your body to the other, this story will also have a familiar tone to it.
After the C5-C6 fusion – My body’s core temperatures go up and down all day.
Again I would like to remind you the reader that many people have very successful cervical fusion surgeries. These are not the people that we see at our center. We see people who have stories that sound like this.
- I have severe neck pain, cervical disc disease, and cervical stenosis. My MRI showed C5-C6 cervical disc herniation and issues at C1-C2. I had C5-C6 fusion. The surgery made my symptoms worse. To help with my symptoms I have had cervical epidural injections, occipital nerve blocks, and Botox for spasms. My symptoms come and go with varying degrees of severity. I recognize that I can make these symptoms and conditions worse by the way I rotate my head. I suffer from balance disorders, dizziness, brain fog, and cognitive dysfunction. I have migraines and occipital headaches. I have touch sensitivity and I have sound sensitivity. My body core temperatures go up and down all day.
This is the type of person who contacts us. In the case of wildly swinging temperature ranges, this condition and symptoms are almost always treated as an afterthought because some of these people have so many problems that they lose track of them. You may be just like them, you have many issues and sometimes you simply lose track of all the things impacting your quality of life.
Later in this article, we will discuss how we may help this patient. But make no mistake, it was a long medical journey that brought this person to this point, it will be another journey to chip away at these symptoms and restore a better quality of life.
Cerebral blood flow, metabolic derangement, and a neurogenic inflammatory response. Problems of the cervical spine.
In the patients described above by the neurologists following a stroke or traumatic injury, the three main components of the cause of thermoregulatory instability are discussed. Let’s discuss these three main issues now in the context of cervical spine instability and an MRI that may show cervical spine herniations and cervical disc disease.
First, the research – cervical spine instability and body and skin temperature dysfunction are connected.
A paper published in 1998 (2) attempted to evaluate the characteristics of the thermovision image (a camera that takes a temperature) in pain syndromes associated with instability of the cervical segment of the spine, to identify the variables and the impact of the characteristics of the thermovision image in the process of rehabilitation, and to specify the suitability of thermovision testing in the evaluation of rehabilitation.
In other words, what these doctors were trying to do was standardize a way that you could take different body temperature readings of people who had cervical spine degenerative disease, plot out a body map of the patient and the different temperature ranges and the variables that caused them, and then you may be able to figure out how to treat this person’s cervical spine problems from the clues the skin temperature ranges gave them.
The results from tests performed in 71 patients indicate that patients with instability of the cervical segment of the spine, in comparison to healthy subjects, are characterized by the high asymmetry of the neck and severe cervical hyperthermia.
In other words, part of the test subject’s neck was hot, other parts were not. If you treated the neck pain successfully, you would be able to demonstrate this by making all parts of the neck have the same skin temperature reading.
Hot and cold skin patches across the body can help show where cervical spine degeneration is
Before we go further into this segment, skin temperature regulation or skin temperature dysfunction can be valuable tools in helping the patient with cervical neck pain and the symptoms and neurologic-type symptoms it is causing the patient. They are not the only tools. We also use other diagnostic aids as described below.
Using acute neck injury research as a guide connecting cardiovascular-like symptoms and temperature dysregulation.
Doctors know that when a patient suffers from severe and sometimes paralyzing neck injury / cervical spinal cord injury, nervous system functions are altered. While this is an acute impact event causing the patient’s post-injury problems, we can see where degenerative cervical spine degeneration may follow a similar path of neck trauma patients.
This is from a November 2019 paper in the Journal of Clinical Neuroscience (3). Here researchers give a basic outline of events connecting temperature dysregulation with cardiovascular-like symptoms.
“Despite the many evaluations conducted to unveil the physiological and thermo logical complications caused to the human body after a cervical spinal cord injury, the fundamental pathophysiology about this type of injury is still inconclusive. . . This (study) attempts to provide a better understanding of the various changes caused to the body after a cervical spinal cord injury. It focuses on the alterations in blood circulation, energy expenditure, sweating, shivering responses, and consequently disruption in body temperature regulation.
- Findings: “Following cervical spinal cord injury, energy expenditure (simply energy) decreases by 10% due to reduction in lean body mass; cardiac output decrements by 27% following the change in arterial blood vessel structure, and finally; thermoregulatory responses were disturbed because of the absence or decrease in vasodilation, vasoconstriction, sudomotor (autonomic activation of sweat glands) and shivering responses.
- Conclusions: “The body undergoes significant thermoregulatory changes following spinal cord injury. Understanding the pathophysiology of spinal cord injury and its effect on the human body can provide us an insight to develop adequate treatment modalities that tackle the problem of thermal dysregulation in people with cervical spinal cord injury.”
In this paper, the findings were directed at loss of energy, muscle atrophy, and loss of vasodilation (increasing blood flow by reducing blood pressure), vasoconstriction (one aspect of vasoconstriction is to slow down blood to areas that are “too cold” so the blood itself does not get cold and cause problems in vital organs. For example, your hands will turn blue before your trunk will) and the seating shivering response. All parts of the neurologic-like and cardiovascular-like symptoms of cervical spine instability.
Thermatomal changes in cervical disc herniations
The title of an October 1999 paper is “Thermatomal changes in cervical disc herniations.” (4) Let’s explore this paper:
“Subjective symptoms of a cool or warm sensation in the arm could be shown objectively by using of thermography with the detection of thermal change in the case of radiculopathy, including cervical disc herniation. However, the precise location of each thermal change at cervical disc herniation has not been established in humans. This study used digital infrared thermographic imaging for 50 controls and 115 cervical disc herniation patients, analyzed the data statistically . . . and defined the areas of thermatomal change in cervical disc herniation C3/4, C4/5, C5/6, C6/7, and C7/T1.”
Building on similar research in the 1998 study cited above (2) these doctors mapped out areas in the arm where temperatures of the arm swung between hot and cold. They theorized that if you trace the nerve root back from these spots of temperature inversion in the arm, you can trace a route back to the problem area in the cervical spine and where a nerve may be impinged. For instance, they found that:
- Thermal change in cervical disc herniation C3/4 included the posterior upper back and shoulder and the anterior shoulder.
- Thermal change in cervical disc herniation C4/5 included the middle and lateral aspect of the triceps muscle, proximal radial region (elbow wrist area), the posterior medial aspect of the forearm, and distal lateral forearm.
- Thermal change in a cervical disc herniation at C5/6 included the anterior aspects of the ulnar, thumb, and second finger and the anterior aspects of the radial region, and posterior aspects of the para-radial region.
- Thermal change in cervical disc herniation C6/7 included the posterior aspect of the ulnar and palmar (palm) region and the anterior aspects of the ulnar region and some fingers.
- Thermal change in cervical disc herniation C7/T1 included the scapula and posterior medial aspect of the arm and the anterior medial aspect of the arm.
The caption of the image below reads: Infrared temperature monitoring of nerve compression. This particular patient’s temperature readings, being lower in the left arm compared to the right, confirmed compression of the C5-C6 nerve distribution to the left.
But this can be a tricky science, in 2020 researchers published these observations in the journal Medicine (5).
“In general, in digital infrared thermographic imaging of patients with unilateral (one-sided) spinal radicular pain, the thermal pattern of the extremities of the side of (the degenerative disc lesions) shows hypothermia (cold skin) compared to the opposite, intact side. However, sometimes, digital infrared thermographic imaging shows hyperthermia (hot skin) on the side of the lesion, and this variation can cause confusion.”
What the researchers did was try to explain this flip-flop in temperature asymmetry.
They compared the data of both hypothermia and hyperthermia patients to clarify the factors determining different thermal characteristics in spinal radiculopathy. Two hundred twenty-four patients were divided into two groups:
- A hypothermia group (180 patients) and a hyperthermia group (44 patients). Then they compared the various factors that could account for this.
They found: In patients with trauma history, acute phase of pain, and severe radicular pain, hyperthermia in digital infrared thermographic imaging is not unusual, and careful interpretation of the digital infrared thermographic imaging results is necessary for proper diagnosis and treatment decisions in spinal radiculopathy.
In other words, in chronic neck pain people, hot and cold can go either way.
These phenomena were also observed in people who suffered from lumbosacral radiculopathy
In many patients we see, they, unfortunately, do not suffer from cervical spine instability, they also suffer from lumbar spinal instability. Researchers are showing that in people who suffer unilateral lumbosacral radiculopathy, they too can suffer from skin temperature changes. Here are the findings of a 2013 paper published in the Annals of Rehabilitation Medicine. (6)
In this study, researchers sought to “clarify the relationship of skin temperature changes to clinical, radiologic, and electrophysiological findings in unilateral lumbosacral radiculopathy and to delineate the possible temperature-change mechanisms involved.”
- One hundred and one patients who had clinical symptoms and for whom there were physical findings suggestive or indicative of unilateral lumbosacral radiculopathy, along with 27 normal controls, were selected for the study, and the thermal-pattern results of digital infrared thermographic imaging (DITI) were performed on the back and lower extremities were analyzed.
- The incidence of disc herniation on MRI was 86%; 43% of patients showed electrophysiological abnormalities.
- On digital infrared thermographic imaging DITI, 97% of the patients showed abnormal average temperature differences in at least one of the 30 (skin) regions of interest, and 79% showed hypothermia on the involved side. Seventy-eight percent of the patients also showed abnormal thermal patterns in at least one of the seven regions. Patients who had motor weakness or lateral-type disc herniation showed some correlations with abnormal digital infrared thermographic imaging findings. However, neither pain severity nor other physical or electrophysiological findings were related to the digital infrared thermographic imaging findings.
- Skin temperature change following lumbosacral radiculopathy was related to some clinical and MRI findings, suggesting muscle atrophy. Digital infrared thermographic imaging, despite its limitations, might be useful as a complementary tool in the diagnosis of unilateral lumbosacral radiculopathy.
What this study concluded was if there were abnormal skin temperature readings in the “regions of interest” the doctor should suspect lumbosacral radiculopathy. At our center, we can have a realistic expectation that if there are zonal abnormal skin temperature readings in certain parts of the body, that cervical spine instability is at the root and that the abnormal skin temperature readings are a result of cervical spine problems in many cases.
Cerebral blood flow and distorted nerve signals – the hypothalamus, the trigeminal nerve, and trigeminal ganglion
The patients we see have a myriad of symptoms that, when deeply investigated, all lead to a common point. Such is the case of patients with cervical neck pain, neurologic-type symptoms, and a long medical journal of seemingly no answers.
It started with whiplash and a concussion.
Here is one such journey. In the examples above, the person suggested that their problems started after a cervical spine fusion. Here is an example where there was no surgery but a bad whiplash and concussion.
I suffered from a whiplash injury and concussion. Months later I started suffering from Trigeminal Neuralgia, Occipital Neuralgia, and migraine. I had vision problems, dilated pupils, swallowing difficulties, parts of my body would get very hot, other parts of my body would get very cold. I would have a lot of sweating on one side, none on the other. I have rapid heart rate, lightheadedness, digestion problems leading to constipation and insomnia. I am in spasms most of the time as I have muscle tightness from my neck through my shoulders. I am in severe and constant pain.
In the problems of thermoregulatory instability, the common point of symptoms including migraine, cluster headache, facial pain, neck pain, sleep deprivation, excessive sweating, and problems of blood flow in and out of the brain may be traced to one explanation of miscommunication between the hypothalamus, the trigeminal nerve, and trigeminal ganglion. Another explanation is arterial and venous compression by the cervical vertebrae. We will explore the first explanation, bad signals between the hypothalamus, the trigeminal nerve, and trigeminal ganglion.
Describing what the hypothalamus is and all the regulatory functions it is responsible for would take pages and pages. In the context of this article, the hypothalamus and its function will be described as it relates to blood flow and temperature regulation.
The hypothalamus is a gland at the base of the brain that sends out hormones and signals to regulate many body functions. Among them are receiving and sending pain signals, temperature regulation or thermoregulation signals, and vasodilation the regulation of blood flow. In fact, the nerve cells or neurons that control vasodilation originate in the hypothalamus.
The trigeminal nerve and ganglia
- The hypothalamus sends instructions for regulating temperature to the trigeminal nerve (Cranial Nerve V) and the trigeminal ganglia. The trigeminal ganglia also work in conjunction with the dorsal root ganglia that runs down the spine. In essence, the trigeminal ganglia control sensory perception including temperature regulation in the face and the dorsal root ganglia control the temperature regulation from the neck on down.
A brief word on the dorsal root ganglion
Let’s have the medical publication Stat Pearls (updated October 2020) explain this for us. (7)
“The dorsal root ganglion (DRG) has a significant clinical application, particularly in its association with neuropathic pain. DRG neurons emerge from the dorsal root of the spinal nerves, carrying sensory messages from various receptors, including those for pain and temperature towards the central nervous system for a response.”
Clearly what is said is that the dorsal root ganglion sends messages about pain and temperature and waits for nervous system response. If the communication network is working well, clear instructions and regulation of temperature are given. If the communication network is impaired, you have the possibility of temperature dysregulation problems.
Myalgic encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS)
In March 2023, researchers at the University of Barcelona, published findings in the International journal of molecular sciences (8)
Circadian alterations in peripheral temperature have been associated with dysautonomia in Myalgic encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS), reflecting alterations in the vasoconstriction/vasodilation process (the widening and narrowing of blood vessels). The peripheral temperature (the skin surface) increases at night due to vessel dilation, in order to favor sleep, while alterations in this process have been related to difficulty in sleep onset (Suggested that dysfunction in the ability of the skin to “heat up” at night creates sleeping difficulties). However, vasoconstriction is due not only to the sympathetic (flight-fight response) effect on the vessels, but also to the regulation of local vessels by endothelial function (the release of substances to help regulate the inner lining of the blood vessels during dilation and constriction), which has been reported to be altered in ME/CFS. Endothelin-1 a strong endothelial vasoconstrictor, has been related to the regulation of the circadian rhythms, and high circulating ET-1 levels have recently been reported in ME/CFS. . . (The researchers) hypothesized that there would be an alteration of the vasoconstrictor/vasodilation process, which might be reflected in temperature variations, and would indicate dysautonomia in ME/CFS.”
What are we seeing in this image? How the temperature regulation communication network may be impaired
We see that the trigeminal nerve can be compressed or impinged upon by the C1-C2-C3 vertebrae. Cervical spine instability that allows for this compression of the trigeminal nerve can create miscommunication and distortion of messages between the hypothalamus, the trigeminal ganglia, and the dorsal root ganglia. In simplest terms, miscommunication or distorted messages can misfire the nerves and create the problems and symptoms mentioned throughout this article including temperature dysregulation and vasodilation, the problems of distorted blood flow messages.
Arterial and venous compression
While cervical spine instability can cause a disruption in the way our brain, brain stem, and nerves communicate signals with one another, cervical spine instability can also cause a disruption of blood flow in and out of the brain. This can explain the many problems of headache, brain fog, dizziness, and other obvious problems related to a “lack of oxygen,” but it may also help us explain other conditions such as body temperature fluctuations from one side to the other.
What are we seeing in this image? How nerves and arteries interweave themselves through the cervical spine
As you can see and probably know from your own first-hand experience with symptoms and conditions, if the C1 or any of the cervical vertebrae shifts or becomes hypermobile, they can compress nerves and arteries. The compression of arteries and veins can lead to many of the symptoms described in this article including the problems of temperature dysfunction.
What are we seeing in this image?
This is a patient’s DMX image captured. The DMX is an x-ray movie. A video is just below this image. In this x-ray, when the patient looks down, a 6 mm space opens between the C1-C2. When the patient looks up, 0 mm, no space. Everything between those two surfaces is compressed. This includes arteries, nerves, and veins.
The problems of temperature asymmetry and cervical spine instability
In our over three decades in helping people with chronic pain, we have seen, from the start, that mysterious symptoms and missing diagnoses often plague people with upper cervical instability and compression of the brainstem. Solving the problem of a missing diagnosis of cervical spine issues causing these mysterious symptoms may be found in dysregulation of temperature control in the body.
While cervical spine and neck instability offers us a good explanation as to the causes of these symptoms, cervical spine and neck instability can also be an umbrella term used to describe many factors. You may have C0-C1 instability, causing some of these symptoms. You may have problems from C3-C7 fusion causing segmental changes in your cervical spine which cause symptoms. You may have compression of any one or all of the cervical nerves. You may have carotid artery compression. You may also have internal jugular vein stenosis. You may also have a combination of some, many, or all these problems depending on the severity of your neck instability. It can of course be overwhelming.
Here is an example: A patient has just completed real-time testing at our center. Real-time meaning we know the results as the test is being performed, this is explained further below. We will sit with the patient and their spouse or partner and then tell them that we believe many of their symptoms are coming from compression of their jugular vein, the compression is being caused by pressure from the cervical vertebrae or a problem with the styloid process at the base of the skull and possible carotid artery syndrome.
We have a very detailed article that goes further into understanding venous compression and internal jugular vein stenosis that helps explain the problems of blood flow. Also see our article Dynamic Analysis of Blood Flow Measurements to the Brain, Brainstem, Cervical Spinal Cord, and Cranial Nerves.
What are we seeing in this image?
A cervical venous system that makes its way to the brain. As you can see if the C1 or any of the cervical vertebrae shift or become hypermobile, they can compress the veins. The compression of veins can lead to blood flow problems and many of the symptoms described in this article including the problems of temperature dysfunction.
Treatments: Addressing cervical ligament laxity and craniocervical instability and cervical spine degenerative disease and instability
Throughout this article, we explored the possibility that cervical spine instability was responsible for the problems, conditions, and symptoms described here including the problems of temperature dysfunction. In this section, we will now explore possible answers to solving your medical mysteries by addressing the laxity of the cervical spine ligaments and a destructive cervical spine curve.
Atlantoaxial instability: C1 and C2 hypermobility causes cervical spine instability and artery, vein, and nerve compression
Atlantoaxial instability is the abnormal, excessive movement of the joint between the atlas (C1) and axis (C2). The bundle of ligaments that support this joint is strong bands that provide strength and stability while allowing the flexibility of head movement and allow unimpeded access (prevention of herniation or “pinch”) of blood vessels that travel through them to the brain.
In a 2015 paper appearing in the Journal of Prolotherapy, (9) our research team wrote that cervical ligament injury should be more widely viewed as the underlying pathophysiology (the cause of) atlantoaxial instability and the primary cause of cervical myelopathy (disease) including the problems I have written about in this article.
The problems of Atlantoaxial instability are not problems that sit in isolation. A patient that suffers from Atlantoaxial instability will likely be seen to suffer from many problems as they all relate to upper cervical neck ligament damage and cervical instability. As demonstrated below this includes cervical subluxation, (misalignment of the cervical vertebrae). One of the causes of Internal jugular vein stenosis is this cervical misalignment and its “pinching,” or “herniation,” not of a disc, but of the arteries and veins. This creates the situation of ischemia (damage to the blood vessels) or in the case of this article internal jugular vein ischemia.
The case for identifying loss of cervical lordosis as the cause of your symptoms
The cervical ligaments are strong bands of tissues that attach one cervical vertebra to another. In this role, the cervical ligaments become the primary stabilizers of the neck. When the cervical ligaments are healthy, your head movement is healthy, pain-free, and non-damaging. The curve of your cervical spine is in correct anatomical alignment.
When the cervical spine ligaments are weakened, they cannot hold the cervical spine in proper alignment or in its proper anatomical curve. Your head begins to move in a destructive, degenerative manner on top of your neck. This is when cervical artery and jugular vein compression can occur.
In our 2014 research led by Danielle R. Steilen-Matias, MMS, PA-C, published in The Open Orthopaedics Journal (10), we demonstrated that when the neck ligaments are injured, they become elongated and loose, which causes excessive movement of the cervical vertebrae. In the upper cervical spine (C0-C2), this can cause a number of other symptoms including, but not limited to, nerve irritation, vertebrobasilar insufficiency with associated vertigo and dizziness, tinnitus, facial pain, arm pain, migraine headaches, and jugular vein compression.
Treating and stabilizing the cervical ligaments can alleviate these problems by preventing excessive abnormal vertebrae movement, the development or advancing of cervical osteoarthritis, and the myriad of problematic symptoms they cause including nerve, vein, and arterial compression.
Through extensive research and patient data analysis, it became clear that in order for patients to obtain long-term cures (approximately 90% relief of symptoms) the re-establishment of some lordosis, (the natural cervical spinal curve) in their cervical spine is necessary. Once spinal stabilization is achieved and the normalization of cervical forces by restoring some lordosis, lasting relief of symptoms was highly probable.
