Trigeminal neuralgia (TN), responsible for facial sensations.

Trigeminal neuralgia (TN) is a chronic nerve condition that causes sudden, severe facial pain, often described as sharp, electric shock-like, or stabbing. Often termed the "suicide disease" due to its excruciating pain, is a chronic condition affecting the trigeminal nerve, which is responsible for sensation in the face. TN can be triggered by everyday activities such as chewing, speaking, touching the face, or even exposure to wind. The condition is more common in older adults, particularly those in their 60s and 70s, and is known to significantly impact a person’s quality of life.

How Common is Trigeminal Neuralgia in Australia?

The incidence of trigeminal neuralgia is approximately 4.5 per 100,000 people per year. Given Australia’s population of around 26.97 million in 2025, this translates to roughly 1,214 new cases annually.

What Causes Trigeminal Neuralgia?

TN occurs when the trigeminal nerve is compressed or irritated, often by a nearby blood vessel pressing against it. This pressure damages the protective myelin sheath around the nerve, causing it to misfire and send pain signals unnecessarily. Other possible causes include:

Multiple sclerosis (MS): TN can be a symptom of MS due to nerve demyelination.
Tumors or cysts: Though rare, growths can press on the trigeminal nerve.
Head trauma or dental procedures: Injury to the nerve may lead to pain syndromes.
Idiopathic cases: In some cases, there is no identifiable cause.

Diagnosis of Trigeminal Neuralgia

Diagnosing TN is based primarily on clinical history and symptom patterns. A healthcare professional will assess the nature, frequency, and triggers of facial pain. MRI scans may be used to rule out tumors, multiple sclerosis, or other structural issues. TN is often confused with dental problems, sinus infections, or temporomandibular joint (TMJ) dysfunction, leading to misdiagnosis and unnecessary dental procedures.

How Does Trigeminal Neuralgia Compare to Other Nerve Conditions?

TN is part of a broader category of neuropathic pain conditions, which arise due to nerve damage or dysfunction. Some comparable conditions include:

Postherpetic Neuralgia (PHN): A chronic pain condition following a shingles infection, often affecting the same nerve pathways.
Occipital Neuralgia: Involves pain in the back of the head due to irritation of the occipital nerves.
Peripheral Neuropathy: Affects nerves in the hands and feet, commonly seen in diabetes.

What makes TN unique is its intensity and unpredictability—patients often describe it as one of the most excruciating types of pain, with attacks triggered by seemingly minor stimuli.

How Do Nerves Work and Why Does TN Cause Such Intense Pain?

Nerves function like electrical wiring in the body, transmitting signals between the brain and different areas. The trigeminal nerve is responsible for facial sensation and has three branches that cover the forehead, cheeks, and jaw.

When a nerve is damaged or compressed, it can misfire, sending abnormal pain signals to the brain. In TN, this dysfunction leads to hypersensitivity, meaning even a gentle touch can cause unbearable pain. Because nerves operate through rapid electrical impulses, any disruption in their function can cause sudden, intense sensations rather than a dull, lingering ache.

How Does Western Medicine Treat Trigeminal Neuralgia?

Western medical treatment for TN focuses on pain management and nerve stabilisation. Common approaches include:

Medications: Anticonvulsants (such as carbamazepine) and muscle relaxants are often prescribed to reduce nerve hyperactivity.
Surgical Interventions: If medications fail, procedures like microvascular decompression (MVD) can relieve nerve compression, or radiofrequency ablation may disrupt pain signals.
Botox Injections: Some patients find relief through Botox, which can temporarily numb nerve activity.

While these treatments may reduce symptoms initially, they may cause side effects such as drowsiness, dizziness, or nerve damage in severe cases.

Trigeminal Neuralgia from a Traditional Chinese Medicine (TCM) Perspective

Traditional Chinese Medicine (TCM) takes a holistic approach to trigeminal neuralgia, focusing on restoring balance in the body's energy (Qi) and improving circulation to the affected area. In TCM, TN is often associated with disruptions in nerve function and facial pain.

Acupuncture is commonly used to regulate nerve activity, improve blood flow, and reduce inflammation. By stimulating specific points on the body, acupuncture helps modulate pain perception and promote natural healing. Many patients report significant pain relief after a series of treatments, with some experiencing long-term improvements.

Herbal medicine in TCM is tailored to the individual’s constitution. It aims to nourish the nerves, clear blockages, and reduce excess heat or wind that may be contributing to nerve irritation. Additionally, lifestyle recommendations such as stress management, dietary changes, and gentle facial massage may be incorporated into the treatment plan to support nerve health and prevent future flare-ups.

How AcuLife can help?

Trigeminal neuralgia is a complex and debilitating condition, but various treatment options exist. Western medicine provides pain management through medications and surgery, while Traditional Chinese Medicine offers a holistic approach using acupuncture and herbal therapy to address the root cause. Given the condition’s severe impact on daily life, a personalised, multi-disciplinary approach is often the best path to relief.
