Quick answer
What is Trigeminal neuralgia?
Trigeminal neuralgia is a condition causing sudden, intense, stabbing or electric-shock-like pain on one side of the face, in the area supplied by the trigeminal nerve. The pain comes in brief bursts and can be set off by ordinary things such as touching the face, chewing, brushing the teeth, talking or a draught of cold air.
- How it is treated: Treatment usually starts with an anticonvulsant medicine that calms the overactive nerve signalling, rather than ordinary painkillers, which tend not to help this kind of pain.
- Self-care: Identifying and gently avoiding personal triggers — such as cold wind, very hot or cold foods, or pressure on a particular spot — can reduce attacks.
- When to seek help: See your GP if you have repeated bouts of sudden, severe facial pain, as this needs assessment and usually referral to a specialist.
What it is
Trigeminal neuralgia is a condition causing sudden, intense, stabbing or electric-shock-like pain on one side of the face, in the area supplied by the trigeminal nerve. The pain comes in brief bursts and can be set off by ordinary things such as touching the face, chewing, brushing the teeth, talking or a draught of cold air. Although each attack is short, it can be severe enough to disrupt daily life, and bouts may last weeks before easing. It is often caused by a blood vessel pressing on the nerve, but it can sometimes point to another underlying cause, which is why proper assessment is important.
How it is treated
Treatment usually starts with an anticonvulsant medicine that calms the overactive nerve signalling, rather than ordinary painkillers, which tend not to help this kind of pain. Carbamazepine is the established first-line choice; if it is not tolerated or not effective enough, other anticonvulsants such as the gabapentinoids may be used. Specialist referral to neurology is recommended, and a scan (usually an MRI) is often arranged to look for an underlying cause. For pain that does not respond to medicines, surgical and other procedures aimed at the nerve or the vessel pressing on it may be considered.

Lifestyle and self-care
Identifying and gently avoiding personal triggers — such as cold wind, very hot or cold foods, or pressure on a particular spot — can reduce attacks. Soft foods during a bad spell, keeping the face warm, and pacing activities that involve a lot of talking or chewing may all help while medication takes effect.
When to get help
When to see a doctor
See your GP if you have repeated bouts of sudden, severe facial pain, as this needs assessment and usually referral to a specialist. Seek prompt advice if the pain is not controlled, if the medicine causes a rash, fever, mouth ulcers or unusual bruising, or if there are new symptoms such as numbness, weakness or problems with vision, hearing or balance, as these may point to another cause that needs investigation.

Answers
Trigeminal neuralgia: frequently asked questions
What medicines are used for trigeminal neuralgia?
The first-line treatment is the anticonvulsant carbamazepine, which dampens the abnormal nerve signalling that causes the pain. If it is not tolerated or not effective enough, other anticonvulsants such as the gabapentinoids may be tried. Ordinary painkillers usually do not help this type of nerve pain.
Why do ordinary painkillers not work?
The pain comes from misfiring of the trigeminal nerve rather than from tissue injury or inflammation, so standard painkillers have little effect. Medicines that stabilise nerve activity, such as carbamazepine, target the problem directly and are far more effective.
Do I need a scan?
A scan, usually an MRI, is often arranged to look for a cause such as a blood vessel pressing on the nerve and to rule out other conditions. This is part of specialist assessment and helps guide treatment, including whether a procedure might help.
What if the medicine does not control the pain?
If medicines do not give enough relief or are not tolerated, your specialist may consider procedures aimed at the nerve or at the blood vessel pressing on it. These options are discussed individually, weighing the likely benefit against the risks.
