Trigeminal Neuralgia (TN): Causes, Symptoms, and Treatment
Trigeminal Neuralgia (TN) is a chronic pain condition affecting the trigeminal nerve, which carries sensations from the face to the brain. It causes sudden, severe, electric shock-like facial pain, often triggered by simple activities like chewing, talking, or touching the face.
Causes of Trigeminal Neuralgia
🔹 Nerve Compression – A blood vessel pressing on the trigeminal nerve.
🔹 Multiple Sclerosis (MS) – Myelin sheath damage leading to nerve dysfunction.
🔹 Brain Tumors – Rare but can put pressure on the nerve.
🔹 Facial Trauma – Injury or surgery affecting the nerve.
🔹 Aging – More common in people over 50.
🔹 Idiopathic (Unknown Cause) – In some cases, no clear cause is found.
Symptoms of Trigeminal Neuralgia
Sudden, intense facial pain (electric shock-like).
Pain lasts from a few seconds to 2 minutes per episode.
Triggered by daily activities – Talking, chewing, brushing teeth, wind on the face.
Typically affects one side of the face (rarely both sides).
Periods of remission (pain-free intervals) that may shorten over time.
Tingling or burning sensation before an attack in some cases.
Diagnosis of Trigeminal Neuralgia
🔹 Neurological Exam – Identifies affected nerve regions.
🔹 MRI Scan – Rules out tumors, MS, or blood vessel compression.
🔹 Pain Assessment – Based on triggers, duration, and characteristics.
Treatment for Trigeminal Neuralgia
1. Medications (First-Line Treatment)
Anticonvulsants – Carbamazepine (Tegretol), Oxcarbazepine, Gabapentin.
Muscle Relaxants – Baclofen.
Tricyclic Antidepressants – Amitriptyline or Nortriptyline (for burning pain).
2. Lifestyle & Home Remedies
✔ Avoid triggers – Chew on the opposite side, avoid cold wind.
✔ Use warm compresses for relief.
✔ Soft diet to minimize pain during chewing.
✔ Reduce stress – Yoga, meditation, deep breathing.
3. Surgical & Advanced Procedures (For Severe Cases)
Microvascular Decompression (MVD) – Relieves nerve pressure from a blood vessel.
Gamma Knife Radiosurgery – Precise radiation to disrupt nerve pain signals.
Radiofrequency Ablation – Destroys pain fibers in the nerve.
Nerve Blocks or Botox Injections – Temporary relief from pain.
When to See a Doctor?
🔹 If facial pain is frequent, severe, and worsening.
🔹 If medications stop working or cause side effects.
🔹 If there are neurological symptoms like numbness or weaknes
