There is no cure for trigeminal neuralgia. Anticonvulsant drugs usually treat the condition successfully, but do not eliminate it. Certain surgeries may fix the problem for months or even years, but the pain may return. Unfortunately, if it does, it may be more severe. It is also possible that surgery for trigeminal neuralgia can cause parts of your face to become permanently numb. Fortunately, most people do find treatment options that help them effectively manage their trigeminal neuralgia.
