Trigeminal Neuralgia: Symptoms, Diagnosis & Treatment
A clear guide to trigeminal neuralgia, covering the sudden facial pain it causes, how it is diagnosed, and treatment options from medication to surgery.
Treatment usually begins with
Specialist Assessment
Diagnostic Imaging
Medication Trial
Care Team Follow-up
Your neurologist will confirm the diagnosis and start with medication before considering a procedure.
You may need this evaluated if...
A trigeminal neuralgia evaluation is recommended when these signs appear:
- Sudden, sharp facial pain lasting seconds to minutes
- Pain is triggered by touch, chewing or brushing teeth
- Pain occurs on one side of the face
- Episodes are becoming more frequent or severe
Facial pain has many causes, but a pattern like this deserves a proper neurological evaluation.
What is Trigeminal Neuralgia?
Trigeminal neuralgia is a nerve condition causing sudden, severe facial pain along the trigeminal nerve, often triggered by everyday activities like eating or touching the face.
Sudden & Severe
Pain comes in short, intense episodes rather than a constant ache.
Trigger-Sensitive
Light touch, chewing or cold air can set off an episode.
Nerve-Related
Caused by irritation or compression of the trigeminal nerve.
Manageable
Medication controls most cases, with surgery reserved for resistant pain.
Common Symptoms
- Sudden, electric shock-like facial pain
- Pain triggered by touch, chewing or speaking
- Pain limited to one side of the face
- Brief pain-free periods between episodes
- Episodes becoming more frequent over time
What Increases Your Risk
A combination of medical, lifestyle and hereditary factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
1. Clinical history
A detailed description of the pain pattern often points to the diagnosis.
2. Neurological examination
Checking facial sensation and reflexes to rule out other causes.
3. MRI of the brain
Imaging identifies possible blood vessel compression of the nerve.
Treatment Approaches
Medical Care
- Anticonvulsant Medication
- Nerve Pain Medication
- Trigger Avoidance Guidance
- Regular Follow-up
Surgical Care
When medication no longer controls the pain, microvascular decompression or other nerve procedures may be recommended based on the cause and severity.
Treatment decisions are based on symptoms, imaging, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- You have occasional, mild facial pain
- You want a second opinion on your current medication
- You want to explore procedure options after medication
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Pain is severe and not responding to medication
- Facial pain is accompanied by numbness or weakness
- Pain is affecting eating, speaking or daily function
