Trigeminal neuralgia (TN) is a nerve disorder. It causes a stabbing or electric shock-like pain in parts of the face.
The pain of TN comes from the trigeminal nerve. This nerve carries the sensations of touch and pain from the face, eyes, sinuses, and mouth to the brain.
TN may be caused by:
Often, no exact cause is found. TN usually affects adults above age 50 years, but it can occur at any age. Women are affected more often than men. When TN affects people younger than 40, it is often due to MS or a tumor.
Symptoms may include any of the following:
Painful attacks of TN can be triggered by common, everyday activities, such as:
The right side of the face is mostly affected. In some cases, TN goes away on its own.
A brain and nervous system (neurologic) exam is often normal. Tests that are done to look for the cause may include:
Your primary care provider, a neurologist, or a pain specialist may be involved in your care.
Certain medicines sometimes help reduce pain and the rate of attacks. These medicines include:
If you are found to have MS as a cause of TN, your health care provider will discuss medicines that can treat the underlying MS.
Short-term pain relief occurs through surgery, but is associated with risk of complications. One surgery is called microvascular decompression (MVD) or the Jannetta procedure. During surgery, a sponge-like material is placed between the nerve and the blood vessel that is pressing on the nerve.
Trigeminal nerve block (injection) with local anesthetic and steroid is an excellent treatment option to rapidly relieve pain while waiting for medicines to take effect.
Other techniques involve destroying or cutting parts of the trigeminal nerve root. Methods used include:
If a tumor is the cause of TN, surgery is done to remove it.
How well you do depends on the cause of the problem. If there is no disease causing the problem, treatment can provide some relief.
In some people, the pain becomes constant and severe.
Complications may include:
Contact your provider if you have symptoms of TN, or your TN symptoms get worse.
