What kind of doctor treats Glossopharyngeal Neuralgia?
A neurologist (a doctor who treats disorders of the brain and nerves) can evaluate this nerve pain. A pain specialist, a doctor who focuses on pain control, may help when the pain is severe. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is glossopharyngeal neuralgia?
Glossopharyngeal neuralgia (GPN) is a rare condition. It causes repeated episodes of severe pain in the tongue, throat, ear, and tonsils. Neuralgia means nerve pain. Doctors think it is caused by irritation of the ninth cranial nerve. This nerve is also called the glossopharyngeal nerve.
Symptoms
The pain may feel jabbing. It usually happens on one side of the head, although in rare cases both sides are involved. Each episode can last from a few seconds to a few minutes. Episodes can happen many times a day and can wake a person from sleep.
The pain is felt in areas linked to the ninth nerve. These include:
- The back of the nose and throat
- The back of the tongue
- The ear
- The throat
- The tonsil area
- The voice box (larynx)
Episodes can be triggered by chewing, coughing, laughing, speaking, swallowing, yawning, sneezing, or cold drinks. Touching the tonsil on the affected side can also set off pain.
Complications may include a slow pulse, fainting, trouble swallowing food and speaking, and side effects from medicines.
Causes and who gets it
Doctors believe GPN is caused by irritation of the glossopharyngeal nerve. In most cases, the source of the irritation is never found. Possible causes include:
- A blood vessel pressing on the nerve
- A growth at the base of the skull pressing on the nerve
- A tumor, or an infection of the throat and mouth, pressing on the nerve
According to NORD, GPN typically occurs in people over age 40. MedlinePlus says GPN usually occurs in people over age 50.
How doctors diagnose it
Tests look for problems that might press on the nerve, such as tumors at the base of the skull. Doctors may order the following tests:
- Blood tests, to check for infection or a tumor
- A CT scan of the head
- An MRI of the head
- X-rays of the head or neck
Sometimes an MRI shows swelling (inflammation) of the glossopharyngeal nerve.
To check whether a blood vessel is pressing on the nerve, doctors may take pictures of the brain arteries. Options include magnetic resonance angiography (MRA), a CT angiogram, and conventional angiography. Conventional angiography uses a dye and X-rays to show the arteries.
Treatment
The goal of treatment is to control pain. Over-the-counter pain medicines are not very effective, according to NORD. The most effective medicines are antiseizure medicines, such as carbamazepine. Antidepressants may help certain people.
Medicines used for this condition can cause side effects.
In severe cases, when pain is hard to treat, surgery to take pressure off the glossopharyngeal nerve may be needed. This is called microvascular decompression. The nerve can also be cut, which is called rhizotomy. Both surgeries are effective. Surgery is considered effective for people who do not benefit from medicines.
If a cause of the neuralgia is found, treatment should control the underlying problem. How well you do depends on the cause of the problem and the effectiveness of the first treatment.
When to see a doctor
Contact your health care provider right away if you have symptoms of GPN. Contact a pain specialist if the pain is severe, to be sure you know all your options for controlling pain.
A slow pulse and fainting may occur when the pain is severe.
Call 911 or go to the emergency room if you have fainting or loss of consciousness, breathing problems, or a change in mental status.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This doctor can help you decide when to contact a pain specialist, such as when the pain is severe.
Common questions
Is glossopharyngeal neuralgia dangerous?
Yes, it can cause complications. A slow pulse and fainting may occur when the pain is severe. Get emergency care if you faint or have trouble breathing.
Can glossopharyngeal neuralgia be treated?
Yes. The goal of treatment is to control the pain. The most effective medicines are antiseizure medicines, such as carbamazepine. Surgery is considered effective for people who do not benefit from medicines.
Do everyday activities trigger the pain?
Yes. Chewing, coughing, laughing, speaking, swallowing, yawning, sneezing, and cold drinks can trigger pain. Touching the tonsil on the affected side can also set it off.
Can GPN make it hard to eat or talk?
Yes. Difficulty swallowing food and speaking is a possible complication of GPN.
