What is trigeminal neuralgia?
Trigeminal neuralgia (TN) is a condition that causes sudden and severe pain in parts of the face. TN is caused by a problem with the trigeminal nerve, which is a nerve that runs from the brain to the face.
What are the symptoms of trigeminal neuralgia?
TN causes sharp and stabbing pain in the cheek, lower face, or around the eye. The pain lasts a few seconds to a few minutes, and usually happens on only 1 side of the face. TN can also cause muscle spasms in the face that happen at the same time as the pain. Most people with TN have repeated episodes of pain.
Often, certain movements or activities make the pain attacks happen. These can include:
- Touching the face
- Brushing the teeth
- Cold air on the face
Will I need tests?
Maybe. Your doctor or nurse should be able to tell if you have TN by learning about your symptoms and doing an exam.
He or she might do tests to get more information about your TN or what’s causing it. These tests can include:
- An MRI or CT scan of your brain – These are imaging tests that can create pictures of your brain
- Tests to check how the nerves and muscles in your face are working
How is trigeminal neuralgia treated?
TN is usually treated with medicine. Doctors can use different types of medicines to treat TN. Most often doctors prescribe a type of medicine normally used to prevent seizures, called antiepileptics. These medicines quiet the nerve signals that cause pain in TN.
For most people, the medicine helps reduce the number of TN attacks they have and makes their pain less severe. But if medicines don’t help enough or cause too many side effects, your doctor might talk with you about other treatment options. These include different types of procedures that quiet the nerve and make it less likely to fire. These minimally invasive treatments are very effective in reducing the intensity and the frequency of attacks. In many instances, they have even been shown to produce complete relief.
