What is trigeminal neuralgia?
Trigeminal neuralgia is a condition causing sudden, severe, electric-shock-like attacks of pain in the face. It affects the trigeminal nerve, which carries sensation from the face to the brain. Attacks usually last from a fraction of a second to about two minutes, often come in bursts, and typically affect one side, most often the cheek, jaw, teeth, gums or lips.
The NHS trigeminal neuralgia guide notes it is more common in women and in people over 50. Attacks are often triggered by light touch, eating, talking or brushing teeth. Some people have periods of remission lasting months or years. Effective trigeminal neuralgia treatment depends on an accurate diagnosis.
What causes trigeminal nerve pain?
| Type | Cause |
|---|---|
| Classical | A blood vessel, usually an artery, presses on the nerve where it leaves the brainstem |
| Secondary | An underlying disease, such as multiple sclerosis or a tumour, affects the nerve |
| Idiopathic | No cause found on MRI |
Facial pain has many other causes, including dental problems, sinus disease, jaw joint disorders, shingles-related pain and other nerve conditions. A doctor or dentist should rule these out. The MedlinePlus trigeminal neuralgia page from the US National Library of Medicine is a useful overview.
How is trigeminal neuralgia diagnosed?
Diagnosis is mainly based on the pattern of symptoms described to a doctor and a neurological examination. An MRI of the brain is usually advised to look for a blood vessel compressing the nerve and to exclude multiple sclerosis or a tumour, especially in younger patients or when surgery is being considered. A dental review is often worthwhile because tooth problems can mimic the pain.
Conventional trigeminal neuralgia treatment
Medicines come first. The UK NICE guideline on neuropathic pain (CG173) recommends carbamazepine as the initial treatment for trigeminal neuralgia. The NHS treatment page also describes other options.
- Carbamazepine: an anticonvulsant that reduces nerve firing. It helps many people but can cause dizziness, drowsiness, and less commonly blood or liver problems and serious skin reactions, so monitoring is needed.
- Oxcarbazepine: a related medicine often better tolerated.
- Other medicines: baclofen, lamotrigine, gabapentin or pregabalin may be tried, usually under specialist guidance.
If medicines stop working or side effects are intolerable, a neurologist or neurosurgeon may discuss procedures:
- Microvascular decompression (MVD): open surgery behind the ear that moves the compressing blood vessel away from the nerve. It is the most invasive option but often gives the longest-lasting relief when a vessel is found. See PubMed research on MVD outcomes.
- Percutaneous procedures: needle treatments through the cheek (radiofrequency thermocoagulation, glycerol injection or balloon compression) that deliberately damage part of the nerve. Recovery is quick, but facial numbness is common and pain often returns over time.
- Stereotactic radiosurgery (Gamma Knife): focused radiation to the nerve root without an incision. NICE has published guidance on Gamma Knife radiosurgery for trigeminal neuralgia. Relief can take weeks to months to start.
Living with trigeminal neuralgia
Alongside medical treatment, practical steps can make attacks easier to manage:
- Keep a pain diary. Note attacks, triggers and medicine doses; it helps your doctor adjust treatment.
- Protect your face from cold wind with a scarf, and use lukewarm water for washing.
- Eat soft foods and chew on the unaffected side during flare-ups, but keep eating and drinking enough.
- Do not stop medicines suddenly. Doses are usually reduced gradually under medical advice, even in remission.
- Keep dental check-ups. Tell your dentist about the condition so triggers are minimised.
- Seek support. Long-term facial pain can affect mood and sleep; patient support groups and psychological help are worthwhile.
Regenerative options: an honest assessment
There is no established clinical evidence that stem cell therapy, PRP therapy or exosome therapy helps trigeminal neuralgia. Research is very limited and mostly at the laboratory or animal stage; see PubMed research on stem cells and trigeminal neuralgia. No regulator in the US, UK or Australia approves stem cells for this condition, and the FDA warns patients about unapproved regenerative products.
Because the proven treatments are effective for many people, we do not recommend travelling for regenerative care as a treatment for trigeminal neuralgia. If someone offers you a stem cell “cure” for facial nerve pain, treat that as a warning sign. Our safety page explains what to ask any clinic.
Who might still talk to our doctors?
Some people with trigeminal neuralgia have other conditions where regenerative care is being studied, or want a second opinion on their imaging and options. A doctor review can help you:
- Understand your MRI findings and what they mean
- Check whether a specialist neurology or neurosurgery referral is the better next step
- Discuss separate musculoskeletal or nerve problems, such as peripheral neuropathy, where evidence differs
Who should not pursue regenerative treatment for facial pain
- Anyone whose trigeminal neuralgia has not yet been tried on carbamazepine or oxcarbazepine
- People with a blood vessel compressing the nerve who are fit for MVD and have not had a surgical opinion
- New facial pain with numbness, weakness, vision or hearing changes, which needs urgent neurological assessment
- Pregnancy, active cancer or active infection
Risks of the main treatments
| Treatment | Main risks |
|---|---|
| Carbamazepine / oxcarbazepine | Drowsiness, dizziness, low sodium, blood and liver effects, rare severe skin reactions |
| Microvascular decompression | Risks of brain surgery, including hearing loss, facial numbness, spinal fluid leak, stroke (rare) |
| Needle procedures | Facial numbness, reduced corneal sensation, pain recurrence |
| Radiosurgery | Delayed relief, facial numbness, pain recurrence |
| Unproven regenerative injections | Unknown benefit, infection, cost and delay of effective care |
Getting a second opinion

Frequently asked questions
What is the first-line treatment for trigeminal neuralgia?
Carbamazepine is the usual first medicine, as recommended by the UK NICE guideline on neuropathic pain. Oxcarbazepine is a common alternative. Ordinary painkillers such as paracetamol do not usually help trigeminal neuralgia.
Can trigeminal neuralgia be cured?
There is no guaranteed cure. Many people control their pain well with medicine. Microvascular decompression surgery can give long-lasting relief for suitable patients when a blood vessel is pressing on the nerve, but pain can return.
Does stem cell therapy work for trigeminal neuralgia?
There is no reliable clinical evidence that stem cell therapy helps trigeminal neuralgia. Research is at a very early, mostly laboratory stage. Proven medicines and procedures should be used first.
What triggers trigeminal neuralgia attacks?
Attacks are often triggered by light touch to the face, such as washing, shaving, brushing teeth, eating, talking or a cool breeze. Triggers vary from person to person.
Do I need an MRI for trigeminal neuralgia?
An MRI is commonly recommended to look for a blood vessel pressing on the nerve, and to rule out other causes such as multiple sclerosis or a tumour. It is especially important before surgery is considered.
How much does trigeminal neuralgia treatment cost?
It depends on the cause and the treatment needed. Send your MRI and reports on WhatsApp and a doctor will review them and tell you honestly whether we can help or whether you should see a neurologist or neurosurgeon.
