Trigeminal nevralgia: Trigeminal neuralgia (tn), also called tic douloureux, characterized by intermittent, shooting pain in the face. The most frequent cause of trigeminal neuralgia is a blood vessel pressing on the nerve near the brain stem. The blood vessels of the brain can result in rubbing against the trigeminal nerve root causing the nerve irritation.
