Trigeminal Neuralgia

Excerpt

Trigeminal neuralgia, previously known as tic douloureux, is a chronic pain condition characterized by recurrent brief episodes of electric shock-like pains affecting the structures innervated by the fifth cranial nerve (CN). CN V, the trigeminal nerve, innervates the forehead, cheek, and lower jaw. Trigeminal neuralgia is most frequently unilateral but can involve one or more divisions of the trigeminal nerve.
