Trigeminal Neuralgia: When to seek a second opinion
Sudden, sharp, shock-like facial pain? Here's how trigeminal neuralgia is diagnosed, what treatments actually help, and why a second neuro opinion can save you from unnecessary surgery.
What is trigeminal neuralgia?
Trigeminal neuralgia (TN) is a chronic pain condition affecting the trigeminal nerve — the fifth cranial nerve that carries sensation from your face to your brain. Patients describe the pain as an 'electric shock' lasting a few seconds to two minutes, often triggered by chewing, brushing teeth, or a breeze on the face.
How is it diagnosed?
TN is a clinical diagnosis. An MRI with FIESTA/CISS sequences is crucial to rule out vascular compression (classical TN) or a secondary cause such as multiple sclerosis or a tumour. Unfortunately many patients get labelled with 'dental pain' and undergo multiple root canals before the neuro cause is identified.
Why a second opinion matters
First-line treatment is almost always medical — carbamazepine or oxcarbazepine. Surgery (microvascular decompression, Gamma Knife, balloon compression) is only indicated if medical therapy fails or causes unacceptable side effects. We routinely see patients being pushed toward surgery when their medical treatment was never optimised. A second opinion from a neurologist experienced in TN can save you from a procedure you don't need.
When to worry (red flags)
See a neurologist urgently if the pain is constant (not paroxysmal), if there's numbness on the face, if vision or hearing changes, or if you're under 40 — these could point to a secondary cause like MS or a mass lesion.
