Trigeminal Neuralgia (TN), also known as tic douloureux, is a chronic pain condition that affects the trigeminal nerve—one of the most widely distributed nerves in the head. It is known for causing sudden, intense, and electric shock-like facial pain that can be debilitating.
📍 The Trigeminal Nerve: An Overview
The trigeminal nerve is the fifth cranial nerve and is responsible for sending sensations from your face to your brain. It has three main branches:
-
Ophthalmic branch (V1) – serves the forehead, eyes, and top of the head
-
Maxillary branch (V2) – serves the cheek, upper lip, and upper teeth
-
Mandibular branch (V3) – serves the lower jaw, lower teeth, and some parts of the ear
Trigeminal Neuralgia typically affects one or more of these branches, usually on one side of the face.
⚡ Symptoms of Trigeminal Neuralgia
-
Sudden, sharp, stabbing, or electric shock-like pain
-
Pain that lasts from a few seconds to a couple of minutes
-
Pain triggered by everyday actions like:
-
Brushing teeth
-
Chewing
-
Speaking
-
Light touch or even a breeze on the face
-
-
Episodes may become more frequent and intense over time
-
Pain is usually on one side of the face
In some people, the pain may be constant but burning and aching instead of sharp. This is often referred to as atypical trigeminal neuralgia.
🎯 What Causes Trigeminal Neuralgia?
The most common cause is compression of the trigeminal nerve, usually by a blood vessel pressing against it. Other causes include:
-
Multiple sclerosis (MS)
-
Tumors pressing on the nerve
-
Nerve damage from injury or surgery
-
Sometimes, no clear cause is found (idiopathic)
🩺 How is Trigeminal Neuralgia Diagnosed?
Diagnosis is based on:
-
Description of pain (sudden, triggered, unilateral)
-
Physical and neurological examination
-
MRI to rule out tumors or multiple sclerosis
-
Response to medication (sometimes used as a diagnostic tool)
💊 Treatment Options
1. Medications
-
Anticonvulsants: such as carbamazepine or oxcarbazepine (first-line treatment)
-
Muscle relaxants: like baclofen, in some cases
-
Tricyclic antidepressants: for atypical TN
2. Surgical Procedures
-
Microvascular decompression (MVD): repositioning the blood vessel pressing on the nerve
-
Gamma knife radiosurgery: focused radiation to damage the nerve
-
Rhizotomy: destroying nerve fibers to block pain
3. Alternative & Complementary Therapies
-
Acupuncture
-
Biofeedback
-
Nutritional supplements (Trigemina Care on our website)
🙋♀️ Who is at Risk?
-
Most common in people over 50
-
More common in women
-
Higher risk in people with multiple sclerosis or other nerve-related conditions
🧘 Coping with Trigeminal Neuralgia
Living with TN can be emotionally and physically exhausting. Support groups, stress management techniques, and counseling can help individuals manage their condition better.
🧾 Final Thoughts
Trigeminal Neuralgia is one of the most painful neurological conditions, but with the right treatment and support, many people find relief. If you or someone you know is experiencing facial pain that fits this description, it's important to seek medical evaluation as soon as possible
