Trigeminal Neuralgia is a chronic condition caused by a misfiring of the trigeminal nerve, causing a brief period of extreme, shooting pain. The nerve can be irritated by an artery or vein compressing the nerve, a tumor, or other disorder. Flashes of pain are also triggered by touching the face, brushing teeth, talking, or wind against the face. People describe the pain as feeling like a sudden burn or an electric shock that is usually felt on only one side of the face.
