Cluster headache produces some of the most severe pain in medicine —— a sharp, burning, or piercing pain centred around one eye, lasting 15 minutes to 3 hours, occurring in clusters of weeks or months separated by remission periods. The attacks are accompanied by autonomic features on the same side as the pain: tearing, nasal congestion, drooping eyelid, or restlessness.
Cluster headache is distinguished from migraine by several features: shorter duration (typically under 2 hours versus 4 to 72 hours for migraine), unilateral orbital pain, prominent autonomic features, and restlessness or agitation during attacks (migraine patients typically prefer to lie still in a dark room).
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for cluster headache.
Common triggers include alcohol during active cluster periods, strong smells, bright light, and changes in sleep pattern. Alcohol triggers are specific to the cluster period —— a glass of wine during remission may cause no problem, but during an active cluster it can trigger an attack within minutes.
Acute treatment aims to abort individual attacks quickly. High-flow oxygen (12 to 15 litres per minute via non-rebreather mask) and specific medications can shorten attacks when taken early. Preventive treatment is used during active cluster periods to reduce attack frequency and severity.
Dr. Jitendra Prasad Yadav evaluates suspected cluster headache at Kathmandu Neurology Clinic (Durbar Marg, Opposite of Yak & Yeti Hotel), distinguishing it from migraine, trigeminal neuralgia, and other causes of facial pain. NMC registration: 8029.
Self-diagnosis is unreliable. Severe unilateral headache should be evaluated to exclude secondary causes and to ensure appropriate classification and treatment.

Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Migraine typically presents as moderate-severe throbbing headache with nausea and/or sensitivity to light or sound, worsened by routine activity. Duration 4–72 hours. Dr. Jitendra Prasad Yadav (NMC 8029) uses ICHD-3 criteria plus your headache diary (frequency, aura, medication days) and red-flag screen to distinguish …
Stress does not cause migraine alone but lowers threshold and increases frequency, especially with irregular sleep and frequent analgesic use. Dr. Jitendra's approach: diary for frequency/medication days, sleep regularity, hydration, caffeine review, and comorbidity screening (anxiety, insomnia, neck pain). The clinic …
