Trigeminal Neuralgia: Symptoms, Causes, Treatment & Exercises

Key Takeaways

• Trigeminal neuralgia affects 0.16% to 0.3% of the population, causing severe electric shock-like facial pain triggered by everyday activities.

• The condition most commonly affects the V2 and V3 nerve divisions, with the right side of the face more frequently involved.

• Treatment options range from medications like carbamazepine to surgical procedures with success rates exceeding 90%.

• Exercise techniques and stress management can help reduce pain frequency and intensity.

• MSK Doctors offers comprehensive trigeminal neuralgia treatment with specialised expertise in both traditional and alternative therapies.

Understanding Trigeminal Neuralgia

Trigeminal neuralgia (TN) is a debilitating chronic pain condition affecting the trigeminal nerve, one of the most widely distributed nerves in the head. While not life-threatening, this condition can be life-altering, with a lifetime prevalence of 0.16% to 0.3% in the general population. 

It causes intense, electric shock-like facial pain that can be triggered by everyday activities, severely impacting quality of life.

What is Trigeminal Neuralgia?

The trigeminal nerve plays a crucial role in facial sensation and function, with three distinct branches serving different areas of the face. The ophthalmic branch (V1) supplies sensation to the eye, upper eyelid, and forehead. 

The maxillary branch (V2) serves the lower eyelid, cheek, nostril, upper lip, and upper gingivae. The mandibular branch (V3) provides sensation to the lower lip, lower gingivae, jaw, and controls the muscles of mastication. 

When this nerve is compromised, typically through compression or other pathologies, it can malfunction, producing extreme pain responses to normally non-painful facial stimuli. The condition most commonly affects the V2 and V3 divisions, with isolated V1 involvement occurring in less than 5% of cases.

Types of Trigeminal Neuralgia

The International Classification of Headache Disorders (ICHD-3) recognizes three distinct types of trigeminal neuralgia: 

• Classical trigeminal neuralgia, the most common form accounting for 80-90% of cases, is caused by vascular compression of the trigeminal nerve, usually involving the superior cerebellar artery in 75-80% of compression cases. 

• Secondary trigeminal neuralgia stems from underlying conditions such as multiple sclerosis, which accounts for 2-4% of cases, or may be due to tumors or other structural abnormalities. This form is more common in younger patients. 

• Idiopathic trigeminal neuralgia occurs when no clear cause can be identified after testing, and may present with either purely paroxysmal pain or include continuous discomfort.

Symptoms of Trigeminal Neuralgia

A sudden, electric shock-like pain that strikes without warning, often affecting one side of the face—with the right side more frequently involved. These intense episodes can last from a split second to two minutes, triggered by something as simple as light touch or everyday activities like brushing your cheek or applying makeup. Interestingly, these painful attacks typically spare you during sleep.

The condition typically begins with mild twinges that can escalate in frequency and intensity over time. Most patients experience unilateral pain, though in rare cases it can be bilateral. Many individuals experience pain-free periods between episodes, but without treatment, symptoms tend to worsen over time.

Treatment Options

Medications play a key role in managing trigeminal neuralgia, helping to control nerve pain and reduce flare-ups.

Medications

Medical management of trigeminal neuralgia typically begins with carbamazepine, an FDA-approved medication that stands as the primary treatment choice. Oxcarbazepine also serves as an alternative first-line option with fewer drug interactions. 

When initial treatments prove insufficient, healthcare providers may prescribe second-line medications including gabapentin, clonazepam, lamotrigine, phenytoin, or baclofen - with the latter showing particular effectiveness when combined with other medications. The medical community continues to investigate newer options, including eslicarbazepine and vixotrigine.

Surgical Intervention

For patients requiring surgical intervention, microvascular decompression represents the most effective long-term surgical option, with success rates exceeding 90% initially. This procedure involves relocating or cushioning blood vessels pressing on the nerve, though approximately 10% of patients experience pain recurrence within two years. 

Rhizotomy is another surgical approach that provides initial pain relief in 80-90% of cases through thermocoagulation, chemical injection, or mechanical balloon compression. However, the five-year recurrence rate for rhizotomy is approximately 53%.

Complementary Therapies

Evidence supports the use of acupuncture, biofeedback, and stress reduction techniques. Botulinum toxin injections have demonstrated significant benefits, achieving 70-87% pain relief in selected cases.

Exercise and Relief Techniques

Neck and Facial Exercises

Neck stretches begin with the head in a neutral position. Turn your head slowly to the right, hold for several seconds, then repeat on the left side. You can also tilt your head forward toward your chest and upward toward the ceiling. 

For facial relief, use fingertips to massage cheeks and jawline in circular motions, which helps reduce muscle tightness and improves blood flow in affected areas.

Progressive Muscle Relaxation

This tension-reduction technique starts with lying comfortably, eyes closed. Tense the muscles in your feet for a few seconds, then release. Work upward through muscle groups—legs, abdomen, chest, arms, and face. 

Focus on each area and consciously relax the muscles. Regular practice helps identify muscle tension patterns and develops effective relaxation skills.

Low-Impact Activities

Yoga combines physical postures, breathing exercises, and meditation to release tension in the neck and shoulders. Tai chi, a gentle martial art, uses slow, controlled movements to promote balance and flexibility while reducing stress. 

Exercise Guidelines

Start with gentle movements and increase duration gradually. Find a balance between activity and rest while monitoring individual triggers. Consistent practice of these techniques can improve pain management abilities and reduce stress associated with trigeminal neuralgia.
