What Is Trigeminal Neuralgia? Facial Nerve Pain Explained
Trigeminal Neuralgia · say it: try-JEM-ih-nul noo-RAL-juhAlso written: tic douloureux, TN, facial nerve pain
Short answer
Trigeminal neuralgia is a nerve condition causing sudden, severe, electric-shock-like pain in one side of the face.
What it means
Trigeminal neuralgia is a condition affecting the trigeminal nerve, which carries feeling from the face to the brain. It causes brief, intense attacks of stabbing or electric-shock-like pain, usually on one side of the face, in the cheek, jaw, teeth, gums or lips. Attacks can be set off by light touch, eating, talking, brushing teeth or a breeze.
It appears on anticonvulsant labels, especially carbamazepine, as an indication, because these medicines calm overactive nerve signals. The same labels have important warnings, such as serious skin reactions (and a genetic test, HLA-B*1502, for people of certain Asian ancestry), blood count problems and many interactions.
Trigeminal neuralgia is different from dental pain, sinus pain or migraine, although it is often first mistaken for toothache. Ordinary painkillers usually do not help much, which is one clue doctors use.
