Trigeminal neuralgia (TN) is pain in the trigeminal nerve of the head. The nerve senses touch, pain, pressure, and temperature. It also helps make saliva and tears. TN causes severe, shooting pain along one side of the face.
TN is more common in women. It is also more common in people aged 50 years or older.
The main symptom is sudden, severe, and stabbing pain on one side of the face. Other problems may be:
Pain that is felt in the inside of the mouth or in the lips, cheek, chin, nostril, ear, or near the eye
Twitching or wincing
Pain that is triggered by things like shaving, washing, or tickling the face
Pain in the eye or forehead (rare)
The pain may last less than 2 minutes. It can happen hundreds of times a day and make it hard to do daily activities. It may come and go for days, weeks, months, or years. It may also get worse over time.
