Neck-Tongue Syndrome treatments

Ross Hauser, MD

Neck-Tongue Syndrome is considered a rare disorder. It is considered so rare that when learning institutes or universities get a patient that is confirmed with Neck-Tongue Syndrome they write up a case history to share with their colleagues because of the rareness of the diagnosis. But how rare is this problem or is it simply misdiagnosed or misunderstood and more apparent than initially thought.

Neck-tongue syndrome is characterized by pain on one side of the neck with or without numbness in the neck, accompanied by simultaneous numbness of the tongue on the same side as the neck pain.  The symptoms occur with the sharp turning of the neck. The neck pain is generally felt in the sub-occipital region. Tongue spasms may occur in some cases.

In our office, we see many patients with numbness or other unusual sensations in the tongue.

In our office, we see many patients with numbness or other unusual sensations in the tongue. While this may be their most troubling symptom it is rarely a symptom that the patients have by itself.

A paper published in the journal BMJ Case Reports (1) by doctors at the Chiropractic and Physiotherapy Department, New York Medical Group, offers this description of the problem.

“Neck-tongue syndrome is a rarely reported disorder characterized by paroxysmal (sudden or acute attacks or) episodes of intense pain in the upper cervical or occipital areas associated with ipsilateral (one-side of the neck and/or head) hemiglossal (one half of the tongue) dysaesthesia (a sensation that is not right or normal) brought about by sudden neck movement. The most likely cause of this clinical entity is a temporary subluxation of the lateral atlantoaxial joint with impaction of the C2 ventral ramus (nerve) against the articular processes (the back of the cervical vertebrae) on head rotation. Neck-tongue syndrome is an under-recognized condition that can be debilitating for patients and challenging for the treating physicians.”

But as mentioned, this problem of one-half-sided tongue numbness is usually one of many problems that a person will suffer from. We often see and hear from people who describe the following challenges they face:

My tongue is always numb and that is just the start of it.

I have problems with my tongue, it is always numb and sometimes it will not even move. It is causing problems with my speech and I have swallowing difficulties. I also have jaw pain, neck pain, and random headaches. I have been going to doctors for years and I have not been getting any help. They think it has to do with the nerves in my neck and if I rest it will go away by itself. This is not happening, it is not going away with rest and in fact, my problem is getting worse. My new set of doctors want to give me a lot of medications. Some are the same ones that I have had before. Now they want to increase my doses so these medications can “do some good.” I am not convinced of that.

My tongue feels numb all the time but there is “nothing wrong with me.”

My tongue feels numb all the time. I also have neck pain and headaches. I have seen regular doctors, ENT doctors, neurologists, chiropractors, herbalists, and others. I have a lot of MRIs and CT scans that say nothing is wrong with me.

An excess of saliva and tongue numbness

I have a problem with excess saliva and a numb tongue. I have been to one specialist after another and they tell me my saliva glands are fine it must be something else. No one has been able to tell me what “something else is.”

I have neck pain, so my doctors think some of my symptoms have something to do with my neck

I have so many problems, but I feel that everything going on with me has something to do with my neck. I have neck pain that is chronic and severe at times. When it is more severe I get worsening symptoms of my other problems. I have difficulty swallowing, my vision is blurryear fullness and a sensation that it is filled with liquid, I have blood pressure spikes, digestive problems, and more. I have seen a cardiologist, an ophthalmologist, and a gastroenterologist, all on the recommendations of my doctor and a neurologist that I must have some time of nerve damage or dysfunction or a pinched nerve in my neck. I have an MRI that shows slight to moderate disc disease in C1-C2.

The neurology of Neck-Tongue Syndrome.

Proprioceptive afferents

A simple way to explain Propriocetptive or proprioception is to have the ability to maintain balance and motion without a visual to assist you. When you run, you do not have to look down at your feet to make sure that they are moving correctly.  You can touch your nose with your eyes closed. You can play an instrument or do other types of work without looking at your fingers.  Your limbs and digits can operate correctly on their own without your eyes guiding them. It is also the ability to understand how much energy or force will be required to open a door or lift an object.

An afferent neuron is a sensory neuron that carries nerve impulses and sensations to the central nervous system terminating the brain.

Now, what about the tongue?

Proprioceptive afferents are tools of sensory perception. Like in the limbs, they sense movement and force in the tongue need to eat, swallow, talk, or simply the movement of sticking your tongue out. If these afferents are compromised, compressed, or impeded in delivering their sensory messages, the tongue will display symptoms of a neurologic kind.

This was explained more than 40 years in a 1980 study in the Journal of Neurology, Neurosurgery, and Psychiatry. (x) Over 40 years later the information is still used in medical research. Here is a simple understanding from that paper:

“Afferents fibres from the lingual nerve traveling via the hypoglossal nerve to the second cervical root provide a plausible anatomical explanation for compression of that root causing numbness of half the tongue.”

The nerve highway out of the tongue

The tongue is trying to send messages to the Central Nervous System and the brain so the brain can process what the tongue is doing and then return messages to the jaw, the facial muscles, etc to help the tongue do what it wants to do. When someone suffers from C1-C2 or atlantoaxial cervical instability, compression occurs along the nerve highway at the lingual nerve by way of the hypoglossal nerve.

Neck-Tongue syndrome has been classified into two categories:

“. . . why patients with neck problems walk around for years without hope or optimism that their problems can be solved”

Other papers besides the research listed above isolated problems of Neck-Tongue Syndrome to problems of cervical neck instability caused by loose and weak cervical ligaments and loose, hypermobile, cervical vertebrae. In my article on cervical neck instability I write:

“The concept of ligament laxity or cervical neck instability being caused by ligament damage is not so simple for doctors to understand. This may be why patients with neck problems walk around for years without hope or optimism that their problems can be solved.” 

Early in 2018, doctors at the University of California, San Francisco (UCSF) Pediatric Headache division and Child Neurology division, teamed with doctors at Boston Children’s Hospital, the University of California, Davis, Department of Neurology and Pain Management Department, researchers from the University of Newcastle, Australia and researchers at  King’s College London, London. What they were looking for were answers to Neck-Tongue Syndrome. What they found was something we have long written about. The problem these patients are challenged with may be treated by addressing supportive structure ligament weakness in the neck and jaw.

In a paper published in Cephalalgia: An International Journal of Headache, (2) these researchers made these observations:

The researchers note 39 case histories

Lastly, these researchers suggested that Neck-Tongue syndrome should be re-instated in the International Classification of Headache Disorders. A guide for treatments for various disorders causing headaches. Neck-Tongue syndrome has been removed from this index for doctors.

Discovering treatment options

The seeming rarity of this disorder has led to numerous studies published in the medical literature describing the patient’s condition and symptom management

In April 2018 doctors in Ireland reported in the Journal of Child Neurology (3) three cases:

In the Journal of Chiropractic Medicine, (4) a case of a 34-year-old female patient who sought treatment at a chiropractic clinic for symptoms involving neck pain associated with left-sided paresthesia of the tongue that had persisted for more than two 2 years.

A case in The Journal of Orthopaedic and Sports Physical Therapy: (5)

OUTCOMES:

NOTE: some of the key points to look at in this research. The main treatment was physical therapy to strengthen the muscles in the cervical spine. This had some positive effects. Physical therapy was given in a way that people with cervicogenic headaches. These would be high-intensity multi-directional exercises.

What the therapists came upon here is that the key to neck-tongue syndrome may be in strengthening the neck.

Below what we will discuss strengthening the cervical neck structure with Prolotherapy injections into the cervical region that has been shown to work on its own in relieving patient symptoms.

Do cervical collars help?

We are going to go back to 1984 and a study published in the Journal of Rheumatology. (6) Here researchers discussed the use of cervical neck collars to help stabilize the neck-tongue syndrome patient’s neck and alleviate symptoms.

At our clinics, our patients discuss the use of cervical collars to help alleviate symptoms until Prolotherapy treatments have induced repair and strength to the cervical region.

An October 2021 review of treatments.

An October 2021 study published in the paper Medicina (7) gives us an updated review of the possibilities of Neck-Tongue Syndrome treatments:

Surgery:

Although non-surgical methods for managing Neck-Tongue Syndrome treatments are common, a study on the surgical management of Neck-Tongue Syndrome treatments confirmed that symptoms were relieved by resolving the compression on the C2 spinal nerve by the protuberant (bulging) atlantoaxial joint

. . .manual therapy, exercise, and cervical collar were found to be effective.

Treatment may include using a neck collar or medication to relieve symptoms, and manual therapy and exercise appear to be appropriate as an intervention.  . .  At this time, symptoms are improved through the effect of manual therapy for the absence of neuromuscular control development of muscles and ligaments due to neurophysiological pathology and structural instability. Therefore, it is suggested that interventions such as spinal manipulation therapy, manual therapy, exercise, and neuromuscular re-education can be helpful as a conservative treatment method.

Neck-tongue syndrome can be compression of the 2nd and 3rd cervical root

Above the updated research discusses the surgical option for symptom alleviation caused by bulging/herniated disc, specifically during sharp neck rotation. When there is upper cervical instability, especially rotatory instability, there is an abnormal subluxation of the lateral atlantoaxial joint upon rotation of the head, which strains the joint capsule and can cause impaction of the C2 ventral ramus against the articular processes of the lateral atlantoaxial joint. Since proprioceptive afferents (sensory nerve fibers) carried by the lingual nerve join at the C1 and C2 roots of the hypoglossal nerve, C1-C2 instability worsened by a quick rotation of the head could cause tongue numbness.

Numb tongue, burning mouth, and other tongue pain from nerve impairment due to cervical instability

Ross Hauser, MD, and Brian Hutcheson, DC discuss the nerves in the neck and face that affect tongue feeling and function, and when staying in prolonged positions can impair the nerves. The cervical instability one can experience during various movements and positions can cause painful symptoms like burning mouth or numb tongue, and difficulty speaking or moving the tongue.

In many cases of Burning Mouth Syndrome or numb tongue, we would recommend a tag-team approach of Prolotherapy injections to strengthen the cervical ligaments to help restore cervical spine stability and cervical curve realignment therapy through the use of specialized chiropractic care.

In almost all the cases of Burning Mouth Syndrome or numb tongue we have seen at Caring Medical, there has been some kind of dental work involved. Whether it’s wisdom teeth being pulled or a crown or a cavity.

Burning tongue / Numb Tongue Syndrome Injection Treatments

Problems with these nerves and cervical spine instability can also cause problems of  Numb Tongue Syndrome where half or more than half of the tongue feels numb tongue and often that occurs with motion.

We can sometimes find that under the certain motions of the neck, as pointed out, loss of tongue sensation with movement, we find under examination that motion of the cervical spine is causing nerve irritation that is impacting the tongue function.

The basic message, if you get rid of the irritation of the C1 or C2 nerve roots by positional changes of the cervical vertebrae, or a diagnostic nerve block, and this alleviates your problems. Then a further exploration of your burning mouth and tongue problems and its cervical spine connection should be explored.

A person with instability of the upper cervical spine, or C1-C2 (atlanto-axial) instability, a rapid rotation of the head can cause the symptoms of neck-tongue syndrome.  Although such treatments as utilizing a cervical collar, performing isometric neck exercises, and posture control, are important modalities in C1-C2 instability, they do not treat the root of the problem of neck-tongue syndrome.  They also provide only temporary relief.

It is our opinion that stabilization of the atlantoaxial facets is what is necessary to resolve neck-tongue syndrome. A more permanent solution option to consider is Prolotherapy. These regenerative injections directed at the weakened ligaments can stimulate repair of the subluxed, unstable atlantoaxial areas. Prolotherapy can help the symptoms of neck-tongue syndrome by stabilizing the excessive movement at the atlantoaxial facets.

Prolotherapy injections for Atlantoaxial instability

In 2015, Caring Medical published findings in the European Journal of Preventive Medicine investigating the role of Prolotherapy in the reduction of pain and symptoms associated with increased cervical intervertebral motion, structural deformity, and irritation of nerve roots.

Twenty-one study participants were selected from patients seen for the primary complaint of neck pain. Following a series of Prolotherapy injections, patient-reported assessments were measured using questionnaire data, including range of motion (ROM), crunching, stiffness, pain level, numbness, and exercise ability, between 1 and 39 months post-treatment (average = 24 months).

We concluded that statistically significant reductions in pain and functionality, indicating the safety and viability of Prolotherapy for cervical spine instability. (8)
