You have trigeminal neuralgia. This is pain caused by irritation of the trigeminal nerve on your face. Symptoms include sudden, sharp pain in your head, face, or jaw. It may feel like an electric shock. It can last for several seconds or minutes. It often happens on only one side of your face. Pain may be set off by things such as moving your jaw when brushing your teeth or eating. Or by a touch on the skin of your face or cold air. The pain may be caused by something irritating the trigeminal nerve, such as a blood vessel pressing against it. But the exact cause of this problem often isn't known. It can be very painful. But the condition isn't dangerous. Some people have underlying health problems causing trigeminal neuralgia, such as multiple sclerosis.
Trigeminal neuralgia is often treated with medicines. These include antiseizure medicines or antidepressants. Certain other treatments may also help. In some cases, you may need surgery. For some people, radiation therapy is needed with a precise tool called gamma knife. This does not make any cuts (incisions). You may need an imaging test, such as a CT or MRI scan of the brain and skull. You will be advised if other health problems need treatment.
