Key facts

Facial pain at a glance.

The essentials, in plain English - the common causes, the dangerous ones and how UK specialists work through them.

  • What it is

    An umbrella term - neuralgic, dental, TMJ, sinus, ear, headache-related, autoimmune and rarely malignant causes of pain in the face.

  • Most common causes

    Dental disease, temporomandibular joint dysfunction, sinusitis and migraine account for the bulk of everyday facial pain.

  • Classic neuralgia

    Trigeminal neuralgia gives brief lancinating shocks in V2 or V3 territory, often with trigger zones on the face.

  • Never miss

    Giant cell arteritis in the over-50s - jaw claudication and scalp tenderness need same-day steroids and specialist review.

  • First-line drugs

    Carbamazepine for trigeminal neuralgia; amitriptyline, gabapentin or pregabalin for post-herpetic and idiopathic facial pain.

  • Definitive options

    Microvascular decompression and gamma knife radiosurgery for classical trigeminal neuralgia in specialist commissioned centres.

Why this guide matters

One symptom, many diagnoses.

Facial pain is one of the hardest symptoms in medicine to sort out. Three principles keep the process safe and useful.

  • Diagnosis first, drugs second

    Empirical analgesia without a specific diagnosis often prolongs suffering. The label - trigeminal neuralgia, TMJ, sinus, PIFP - drives everything.

  • Never miss GCA or cancer

    Two rare causes must be excluded in every clinic - giant cell arteritis in the over-50s and head and neck cancer whenever pain is unexplained and persistent.

  • Use the MDT

    The best outcomes come from specialist facial pain clinics that combine neurology, neurosurgery, ENT, dentistry, rheumatology and pain psychology.

How the diagnosis is made

From first symptom to a clear plan.

The steps a UK neurologist, dentist or facial pain specialist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Detailed pain history

    Character, distribution, duration, triggers, autonomic features and diurnal pattern - the history usually makes the diagnosis.

  2. 02

    Assessing

    Cranial nerve examination

    Trigeminal branches (V1, V2, V3), facial nerve, corneal reflex and the rest of the cranial nerves.

  3. 03

    Assessing

    Dental and ENT screen

    Percussion of teeth, sinus tenderness, otoscopy and jaw movement - the commonest treatable causes are here.

  4. 04

    Confirming

    MRI head with neurovascular

    Rules out secondary trigeminal neuralgia (MS, tumour) and images the trigeminal root entry zone for neurovascular compression.

  5. 05

    Confirming

    ESR, CRP and FBC

    Same-day if giant cell arteritis is suspected - start high-dose steroid before biopsy if the picture fits.

  6. 06

    Planning

    Specialist facial pain clinic

    MDT input - neurology, neurosurgery, ENT, dentistry, rheumatology, pain medicine and psychology.

  7. 07

    Planning

    Targeted onward referral

    Head and neck 2-week wait for suspected malignancy; neurosurgery for MVD or gamma knife; specialist dentistry for occlusal disease.

Typical timeline: urgent presentations same day, MRI and specialist clinic within weeks.

Symptoms

What facial pain can look like.

The patterns that point to trigeminal neuralgia, cluster headache, TMJ, giant cell arteritis and other treatable causes.

  • Lancinating electric shocks

    Brief unilateral stabs in V2 or V3 territory triggered by light touch, chewing or wind - classical trigeminal neuralgia.

  • Deep throat, ear and tongue pain

    Swallowing or talking triggers a stab into the ear or tongue base - glossopharyngeal neuralgia.

  • Severe unilateral orbital pain

    Cluster headache - excruciating retro-orbital pain with tearing, nasal blockage and restlessness, often at night.

  • Jaw pain on chewing

    TMJ dysfunction and myofascial pain, or in older patients jaw claudication from giant cell arteritis.

  • Facial rash and burning pain

    Herpes zoster of the trigeminal nerve, or post-herpetic neuralgia weeks after the rash has healed.

  • Persistent dull ache

    Continuous poorly localised facial pain without a structural cause - persistent idiopathic facial pain (PIFP).

  • Burning tongue and mouth

    Burning mouth syndrome - a chronic oral dysaesthesia most common in postmenopausal women.

  • Red flag - persistent or numb face

    Progressive facial numbness, weight loss, lymphadenopathy or a non-healing ulcer needs urgent head and neck cancer review.

Treatment

How facial pain is treated in the UK.

Treatment is diagnosis-specific. Neuralgias respond to sodium channel blockers and, when refractory, to microvascular decompression or gamma knife. Dental, TMJ, sinus and headache causes each have their own ladder. GCA is a same-day steroid decision.

  • Carbamazepine

    First-line for classical trigeminal neuralgia - titrated slowly under specialist guidance with sodium and blood count monitoring.

  • Oxcarbazepine and lamotrigine

    Second-line neuralgia options when carbamazepine is not tolerated - specialist-initiated.

  • Gabapentin and pregabalin

    Useful for post-herpetic neuralgia, glossopharyngeal neuralgia and neuropathic facial pain after nerve injury.

  • Amitriptyline and duloxetine

    Backbone of medical therapy for persistent idiopathic facial pain and burning mouth syndrome, often via specialist pain clinics.

  • Microvascular decompression

    Gold-standard operation for classical trigeminal neuralgia with imaging-confirmed neurovascular compression. See /treatments/microvascular-decompression/.

  • Gamma knife radiosurgery

    Non-invasive stereotactic option for trigeminal neuralgia when open surgery is unsuitable. See /treatments/gamma-knife-radiosurgery/.

  • TMJ care and botulinum toxin

    Splints, jaw physiotherapy, occlusal review and targeted botulinum toxin for masseter and temporalis pain. See /treatments/botox-medical-neurological/.

  • High-dose steroids for GCA

    Same-day prednisolone for suspected giant cell arteritis, with rheumatology follow-up, temporal artery biopsy or tocilizumab where indicated.

Red flags

When facial pain needs urgent attention.

Most facial pain is manageable in primary and specialist care. These are the situations where hours matter.

  • Giant cell arteritis

    New temporal headache, jaw claudication or visual change over 50 - start high-dose steroid immediately and refer for same-day rheumatology or ophthalmology review.

  • Progressive facial numbness

    Loss of sensation across a trigeminal branch, hearing change or facial weakness needs urgent imaging to exclude a skull-base or cerebellopontine angle lesion.

  • Suspected head and neck cancer

    Persistent unexplained oral, tongue or facial pain, a non-healing ulcer, neck lump or unilateral nasal blockage needs a 2-week-wait referral.

  • Cluster headache attack

    Severe unilateral orbital pain with autonomic features - high-flow oxygen and subcutaneous sumatriptan work fast; urgent neurology if new.

  • Ramsay Hunt syndrome

    Ear pain with a vesicular rash and facial weakness - start antiviral and steroid within 72 hours to protect the facial nerve.

  • Odontogenic infection with spread

    Facial swelling, trismus, fever or difficulty swallowing after dental pain needs same-day maxillofacial assessment.

  • Trigeminal neuralgia under 40

    Consider multiple sclerosis or a structural cause - MRI is essential rather than empirical medication alone.

  • Suicidality

    Chronic facial pain carries a high mental-health burden. Low mood or suicidal thoughts need urgent GP or crisis support.

  • Acute vision loss

    Any sudden loss of vision alongside facial pain is an ophthalmic emergency.

Living with it

Chronic, but usually controllable.

Four things that make the biggest difference day to day - track, sleep, team and mind.

A quiet reminder

A specific diagnosis is worth waiting for.

Once the label is right, most facial pain conditions have a clear evidence-based ladder that leads to real relief.

  1. 01 Track

    Keep a pain diary

    Character, triggers, sleep and menstrual pattern - a two-week diary usually clarifies the diagnosis.

  2. 02 Sleep

    Protect your sleep

    Poor sleep worsens every chronic facial pain syndrome, and shifts trigeminal autonomic cephalalgias into higher gear.

  3. 03 Team

    Use the MDT

    A specialist facial pain clinic brings neurology, dentistry, ENT, rheumatology and pain psychology into one plan.

  4. 04 Mind

    Address the psychological load

    CBT and pain psychology are proven components of care for persistent idiopathic facial pain and burning mouth syndrome.

Frequently asked

Everything we get asked about facial pain.

Quick answers on trigeminal neuralgia, imaging, surgery, GCA and self-care while waiting.

  • What is facial pain?

    Facial pain is an umbrella term covering pain anywhere in the face, jaw, mouth or ears. Causes range from dental disease, TMJ dysfunction and sinusitis to nerve conditions such as trigeminal or glossopharyngeal neuralgia, headache syndromes such as cluster headache and migraine, post-herpetic pain, autoimmune conditions such as giant cell arteritis and, rarely, head and neck cancer.

  • How is trigeminal neuralgia different from other facial pain?

    Classical trigeminal neuralgia gives very brief, severe, electric-shock pains in one side of the face, usually in the cheek or lower jaw, triggered by light touch, chewing, brushing teeth or wind. Between attacks the face feels normal. Persistent aching or burning pain suggests a different diagnosis such as persistent idiopathic facial pain or a dental cause.

  • What tests will I need?

    Most patients need a detailed history and examination, a dental and ENT screen and an MRI of the head with dedicated neurovascular sequences to look at the trigeminal nerve. If giant cell arteritis is possible, ESR, CRP and a full blood count are checked the same day, sometimes with a temporal artery biopsy or ultrasound.

  • When is surgery considered for trigeminal neuralgia?

    When medication fails or is not tolerated, and MRI shows a blood vessel compressing the trigeminal nerve, microvascular decompression is the gold-standard operation. Gamma knife stereotactic radiosurgery, balloon compression, glycerol rhizotomy and radiofrequency ablation are alternatives in specialist commissioned neurosurgical centres.

  • Why is temporal arteritis such an emergency?

    Giant cell arteritis can cause irreversible blindness within hours if untreated. In anyone over 50 with a new headache, jaw claudication, scalp tenderness or visual change we start high-dose prednisolone immediately and arrange same-day rheumatology or ophthalmology review, with temporal artery biopsy or ultrasound to confirm.

  • What can I do at home while waiting for a diagnosis?

    Keep a pain diary, protect your sleep, avoid known triggers, take simple analgesia and see your dentist to rule out treatable dental disease. Seek urgent care for any red flags - sudden visual change, progressive numbness, facial weakness, a non-healing ulcer or a rapidly growing neck lump.
