Understanding Cluster Headaches

Cluster headaches are a severe and intensely painful form of primary headache disorder, often described as one of the most excruciating types of pain known in medicine. They occur in cyclical patterns or “clusters,” with frequent attacks over several weeks or months, followed by periods of remission.

Typical symptoms include:

  • Sudden, severe, burning, or stabbing pain around one eye or temple
  • Attacks lasting 15 minutes to 3 hours, occurring up to several times per day
  • Red, watery eye on the affected side
  • Nasal congestion or runny nose during attacks
  • Restlessness or agitation — patients often find it impossible to stay still
  • Attacks frequently occur at the same time each day, often waking sufferers at night

Cluster headaches are thought to involve abnormal activation of the trigeminal nerve and hypothalamus, affecting both pain signalling and autonomic functions. They predominantly affect men and are often misdiagnosed as sinus pain or migraine. Because of the severity and distinct timing of symptoms, specialist input is vital for accurate diagnosis and treatment.

How We Diagnose

At Wessex Pain Clinic, our consultants take a detailed clinical history, focusing on the frequency, duration, and pattern of attacks, as well as associated symptoms.

AN examination is performed to rule out other causes of severe unilateral head pain such as trigeminal neuralgia, migraine, or intracranial pathology.
MRI imaging of the brain may be arranged to exclude rare structural causes.

Diagnosis is usually clinical. Our priority is to ensure timely, accurate identification and prompt initiation of effective therapy.

Lifestyle and Complementary Therapies

While lifestyle changes cannot prevent cluster cycles, managing triggers such as alcohol, irregular sleep, and strong odours can help reduce attack frequency during active periods.

Our pain psychology and rehabilitation team supports patients in coping with anxiety, sleep disruption, and the emotional impact of severe recurring pain. Hydrotherapy and relaxation-based physiotherapy can aid recovery between bouts.

We provide an individualised care plan, combining medical, psychological, and physical therapies to improve function and resilience.

At Wessex Pain Clinic, we work as a team and meet regularly to discuss complex, treatment resistant or unusual cases. As such you will often receive the expertise of several pain consultants. We believe that we are one of very few pain clinics to offer this.

Medications

Acute (abortive) treatments aim to stop attacks quickly:

  • High-flow oxygen therapy via a face mask — one of the most effective and safest treatments
  • Triptans, usually sumatriptan injections or nasal sprays, to shorten and abort attacks

Preventive (prophylactic) medications reduce the frequency and intensity of attacks during a cluster period.

Interventional Procedures

For patients with chronic or treatment-resistant cluster headaches, we may offer

  • Occipital nerve blocks to reduce attack frequency and severity
  • Sphenopalatine ganglion (SPG) blocks or radiofrequency procedures for targeted pain pathway modulation
  • Occipital nerve stimulation (neuromodulation) in collaboration with specialist centres for refractory cases. PENS (Percutaneous Electrical Nerve Stimulation).
Our treatment approach for cluster headache is comprehensive, urgent, and multidisciplinary, focusing on both rapid relief during attacks and prevention of recurrence.
