Cervicogenic Dizziness: Causes, Symptoms, and UK Treatment Options

Cervicogenic dizziness is a clinical syndrome characterized by a sensation of unsteadiness, light-headedness, or disequilibrium that originates from the cervical spine (the neck). Unlike true vertigo, where the room feels like it is spinning, this condition typically causes a feeling of being 'off-balance' or 'spaced out'.

In the UK, it is often seen in patients who have a history of neck trauma, such as whiplash, or those suffering from chronic neck stiffness due to cervical spondylosis. The underlying theory is that faulty sensory input from the joints and muscles in the neck confuses the brain's balance system, which normally coordinates signals from the eyes and inner ears.

Patients in the UK frequently describe cervicogenic dizziness as a vague sense of swaying that is worsened by specific neck movements or by keeping the head in one position for too long (such as working at a computer). Key symptoms include:

• Unsteadiness: A feeling that you are not quite stable on your feet, often lasting minutes to hours.
• Neck Pain and Stiffness: Most patients report discomfort in the upper neck or the base of the skull.
• Headaches: Specifically cervicogenic headaches that radiate from the back of the head to the temples.
• Reduced Mobility: Difficulty turning the head fully from side to side without increasing the sensation of light-headedness.

It is important to note that this condition rarely causes hearing loss or tinnitus; if those are present, the cause is more likely to be an inner ear issue like Meniere's disease.

The precise mechanism of cervicogenic dizziness involves a mismatch in 'proprioception'—your body's ability to sense its position in space. When the neck is injured or inflamed, the nerves (mechanoreceptors) in the cervical joints send distorted signals to the brain.

Common Causes in the UK

• Whiplash: Acceleration-deceleration injuries common in road traffic accidents.
• Cervical Spondylosis: Age-related wear and tear of the spinal discs and joints.
• Poor Posture: Long periods of 'tech neck' or slouching, which puts strain on the suboccipital muscles.
• Herniated Discs: Pressure on the nerves in the neck can lead to both pain and balance disturbances.

Diagnosis of cervicogenic dizziness is primarily a 'diagnosis of exclusion'. This means that a GP must first ensure that the dizziness is not caused by the cardiovascular system, the brain, or the inner ear. Under NHS and NICE guidance, a clinician will review your medical history and perform physical tests.

These may include the 'neck torsion test', where the clinician holds your head still while you rotate your body on a swivel chair. If this triggers dizziness, it suggests the neck is the source. However, no single scan can 'prove' the condition exists, so a thorough physical assessment is vital.

Management focuses on treating the underlying neck dysfunction to resolve the dizziness. The following options are standard in UK practice:

Physiotherapy and Manual Therapy

NICE guidelines suggest that manual therapy and specific neck exercises are the most effective treatments. A physiotherapist can help with gentle mobilisations, postural correction, and strengthening the deep neck flexor muscles.

Vestibular Rehabilitation

If the dizziness has caused you to become fearful of movement, vestibular rehabilitation therapy (VRT) can help retrain your balance system. This involves specific eye and head movements to reduce sensitivity to motion.

Medication

While 'dizziness pills' (like prochlorperazine) are rarely helpful for this specific condition, GPs may prescribe paracetamol or ibuprofen to manage the neck pain that triggers the symptoms. In cases of significant muscle tension, a short course of muscle relaxants might be considered.

If you are experiencing persistent unsteadiness alongside neck discomfort, you can speak to a GP online for a preliminary assessment. An online consultation is a convenient way to discuss your symptoms, review your medical history, and determine if your dizziness fits the pattern of a cervicogenic issue.

A UK online doctor can provide advice on self-care, discuss ergonomics for your workstation, and, if appropriate, provide a sick note if your symptoms make it unsafe for you to work or drive. They can also help rule out other common causes of dizziness, such as BPPV or anxiety-related light-headedness, and advise you on when a face-to-face physical examination is necessary.

In addition to professional treatment, there are steps you can take at home to manage symptoms:

• Heat Therapy: Using a warm wheat bag on the neck to soothe tight muscles.
• Ergonomic Adjustments: Ensuring your computer screen is at eye level to avoid prolonged neck flexion.
• Gentle Stretching: Performing slow, controlled neck rotations and side bends as tolerated.
• Stress Management: High stress levels can lead to increased neck tension, which may worsen the sensation of unsteadiness.
