Trigeminal neuralgia (TN) is a neurological pain disorder affecting the trigeminal nerve — the major sensory nerve responsible for much of the sensation in the face.

It is typically characterised by sudden, severe episodes of facial pain that may feel like an electric shock, stabbing sensation or intense jolt. Attacks can be triggered by otherwise harmless activities such as brushing the teeth, chewing, talking, washing the face or exposure to cold air.

For some people, trigeminal neuralgia can become extremely disruptive. Fear of triggering another attack may affect eating, speaking, sleeping, social activities and everyday life.

At Vitality Chiropractic Australia in Mill Park, Melbourne, we believe trigeminal neuralgia deserves careful assessment rather than simply treating facial pain in isolation.

Because TN is a neurological condition with several possible causes, appropriate medical assessment and diagnosis are important. Chiropractic care may be considered as an adjunctive approach when there are co-existing musculoskeletal factors such as neck or jaw dysfunction, muscle tension or movement-related symptoms.

If you have new, unexplained or severe facial pain, particularly if you have numbness, weakness or other neurological symptoms, medical assessment should take priority.

What Is Trigeminal Neuralgia?

Trigeminal neuralgia is a disorder involving the trigeminal nerve, also known as the fifth cranial nerve (CN V).

The trigeminal nerve has three major divisions:

Ophthalmic division — V1

Provides sensation to areas including:

• The forehead
• Upper eyelid
• Nose
• Front of the scalp

Maxillary division — V2

Provides sensation to areas including:

• The cheek
• Upper lip
• Upper jaw
• Side of the nose

Mandibular division — V3

Provides sensation to areas including:

• Lower jaw
• Lower lip
• Chin
• Parts of the mouth

The mandibular division also has an important motor function because it supplies muscles involved in chewing. Trigeminal neuralgia most commonly produces pain within one or more of these distributions, usually affecting one side of the face.

What Causes Trigeminal Neuralgia?

There is not one single cause of all trigeminal neuralgia. Modern classification broadly distinguishes between classical TN, idiopathic TN and secondary TN.

Classical Trigeminal Neuralgia

Classical TN is generally associated with neurovascular contact involving the trigeminal nerve, where a blood vessel is in contact with the nerve in a way that can contribute to its dysfunction. Importantly, simply seeing a blood vessel touching the trigeminal nerve on an MRI does not automatically prove that it is responsible for a person’s symptoms. Clinical findings and imaging need to be considered together.

Idiopathic Trigeminal Neuralgia

Some people have typical trigeminal neuralgia symptoms but no definitive underlying cause is identified despite appropriate investigation. This is generally classified as idiopathic TN.

Secondary Trigeminal Neuralgia

TN-like symptoms can occasionally occur because of another neurological or structural condition. Potential causes include:

• Multiple sclerosis
• Tumours or other structural lesions
• Other neurological disorders
• Previous injury or pathology affecting the trigeminal system

This is one reason appropriate diagnostic assessment is important. MRI is recommended as part of the work-up for suspected TN because clinical symptoms alone cannot reliably exclude secondary causes.

Trigeminal Neuralgia Symptoms

The most characteristic symptoms include:

1. Sudden facial pain

Pain often begins abruptly and can be extremely intense.

2. Electric-shock sensations

Patients frequently describe the pain as an electric shock, jolt or stabbing sensation.

3. Short-lasting attacks

Individual attacks are generally brief, although repeated attacks can occur over an extended period.

4. One-sided facial pain

Classical TN usually affects one side of the face.

5. Triggered attacks

Light touch, chewing, speaking, brushing the teeth or cold air may trigger an episode.

6. Pain following a predictable facial distribution

Pain typically follows the territory of one or more branches of the trigeminal nerve.

7. Avoidance of normal activities

Severe or frequent attacks can cause people to avoid eating, talking, brushing their teeth or touching their face.

How Is Trigeminal Neuralgia Diagnosed?

There is no single blood test that confirms trigeminal neuralgia. Diagnosis generally involves a detailed clinical history and neurological assessment. A medical practitioner or neurologist may consider:

Clinical history

Questions may include:

• Where exactly is the pain?
• Is it one-sided or bilateral?
• How long does each attack last?
• What does the pain feel like?
• How frequently does it occur?
• What triggers it?
• Are there symptoms between attacks?
• Has the pattern changed?
• Are there any other neurological symptoms?

Neurological examination

The trigeminal nerve and other cranial nerve functions may be assessed.

MRI

MRI is commonly recommended when TN is suspected because imaging can help investigate potential neurovascular contact and identify alternative or secondary causes. The purpose is not simply to “find something on a scan”, but to help determine whether there is an identifiable neurological or structural explanation for the symptoms.

Trigeminal Neuralgia Treatment

Treatment depends on the individual’s diagnosis, symptom severity, underlying cause and response to previous treatment.

Medical management

Medication is an important part of evidence-based treatment for trigeminal neuralgia. Carbamazepine and oxcarbazepine are recognised first-line pharmacological treatments for TN. Other medications may sometimes be considered by a treating neurologist or specialist when first-line treatment is ineffective, poorly tolerated or insufficient. Medication decisions should be made with an appropriately qualified medical practitioner.

Can Chiropractic Care Help Trigeminal Neuralgia?

This is an important question — and one that deserves an honest answer. Chiropractic care is not considered a primary treatment for the neurological cause of classical trigeminal neuralgia. There is also insufficient evidence to claim that spinal adjustment can directly decompress the trigeminal nerve or correct the underlying cause of classical TN. However, some people with facial pain also have co-existing musculoskeletal problems involving the:

• Upper cervical spine
• Jaw
• Temporomandibular joint
• Neck muscles
• Upper thoracic region
• Postural or movement patterns

These problems can contribute to additional pain, muscle tension, reduced movement and functional limitation. In these circumstances, appropriately selected conservative care may form part of a broader management strategy.

At Vitality Chiropractic Australia, our role is therefore to assess whether there is a musculoskeletal component that we can reasonably and safely address, rather than suggesting that chiropractic care replaces neurological diagnosis or medical treatment.

What About Atlas Orthogonal Chiropractic?

Vitality Chiropractic Australia has particular experience with Atlas Orthogonal techniques and upper-cervical assessment. However, we believe it is important to distinguish a technique that may be used to address associated musculoskeletal dysfunction from a proven treatment for the underlying neurological pathology of trigeminal neuralgia.

If upper-cervical treatment is considered appropriate after assessment, it should be incorporated into an individualised management strategy based on the person’s presentation, tolerance and clinical goals. It should not be presented as a replacement for neurological investigation or evidence-based medical treatment.

What Can Make Trigeminal Neuralgia More Difficult To Manage?

One of the most challenging aspects of TN is the unpredictability of attacks. People may begin avoiding normal activities because they are worried about triggering pain.

This can lead to:

• Reduced food intake
• Avoidance of social interaction
• Fear of brushing the teeth
• Reduced physical activity
• Poor sleep
• Increased stress
• Anxiety around pain triggers
• Reduced quality of life

The severity of TN should therefore be considered in terms of more than pain intensity alone. The impact on eating, speaking, sleeping, work, relationships and confidence is also important.

Trigeminal Neuralgia & Stress

Stress does not necessarily cause trigeminal neuralgia, and it should never be used to dismiss severe facial pain as “just stress”. However, living with unpredictable and severe pain can understandably increase psychological stress. A comprehensive approach may therefore include appropriate psychological and supportive care alongside medical treatment. The European Academy of Neurology guideline specifically recognises the importance of psychological and nursing support in TN management.

Trigeminal Neuralgia & Neck Pain

The upper cervical region and facial structures have complex neurological relationships, and people with facial pain may also experience neck pain or muscular tension. However, this does not mean that neck dysfunction is the underlying cause of trigeminal neuralgia.

At Vitality Chiropractic Australia, we therefore assess neck-related findings as potentially associated musculoskeletal factors, rather than automatically attributing TN to cervical “misalignment”. This distinction is important for providing responsible, evidence-informed care.

Trigeminal Neuralgia: Recovery And Long-Term Management

TN does not necessarily follow a simple recovery pathway. Some people experience periods of remission followed by recurrence, while others have persistent or progressively difficult symptoms. The goal of management is therefore not simply to “fix the neck”.

A successful management strategy may involve:

Diagnosis → Medical management → Symptom control → Functional recovery → Long-term management

Where appropriate, conservative musculoskeletal care can sit alongside this process rather than replacing it.
