Trigeminal neuralgia

Also called Tic douloureux or Facial nerve pain

Trigeminal neuralgia is sudden, severe facial pain, often described as like an electric shock, in the jaw, teeth, gums, lips or around the eye. Attacks can be triggered by everyday things like touching the face, eating, talking or a breeze. It is usually caused by a blood vessel pressing on the trigeminal nerve and is more common in people over 50. It can be linked to multiple sclerosis.

What it is

Attacks can last from a few seconds to about 2 minutes and may come in bursts for days or months.

An anti-seizure medicine called carbamazepine is usually the first treatment. If medicines do not help, surgery or other procedures may be offered.
