Cluster Headache
Also known as: Cluster headache, Cluster headache attack, Trigeminal autonomic cephalalgia, TAC, Suicide headache, Horton syndrome, Cluster attack, Episodic cluster headache, Chronic cluster headache
Cluster headache is a primary headache disorder characterised by extremely severe, strictly unilateral pain located around the eye or temple, occurring in attacks that last 15 to 180 minutes and recur from every other day to up to eight per day. Attacks are accompanied by ipsilateral autonomic features such as redness and watering of the eye, nasal congestion or runny nose, sweating or a drooping eyelid, and patients are typically restless or agitated during an attack. The condition occurs in bouts (cluster periods) lasting weeks to months, separated by remission, and is far more common in men; it is classified among the trigeminal autonomic cephalalgias [1][2]. Acute attacks are treated with high-flow oxygen and subcutaneous or intranasal triptans, while preventive medicines such as verapamil are used during cluster periods, and neuromodulation is considered in refractory disease. Diagnosis is clinical, based on the International Classification of Headache Disorders, and imaging is used to exclude other causes when features are atypical [1][2]. In Chinese medicine, cluster headache overlaps with Tóu Fēng and Tòng Fēng, with mechanisms including Liver Yang rising or Liver Fire flaring upward, Wind-Heat harassing the upper body, Qi and Blood stasis in the head channels, Phlegm-Heat obstructing the clear Yang, and Kidney deficiency failing to nourish the head. Pattern differentiation must respect the strict unilateral, orbital and periodic character of the disorder, and acupuncture is adjunctive to specialist neurological management [1][2][3].

Lifestyle & Diet
- •Abstain completely from alcohol during cluster periods, as it commonly triggers attacks [1].
- •Maintain highly regular sleep and meal times; sleep disruption can worsen bout stability.
- •Avoid strong smells such as solvents, perfumes and petrol, which can trigger attacks in some people.
- •Keep an attack diary recording time, duration, severity and triggers.
- •Carry prescribed acute treatment at all times during a cluster period.
- •Manage stress and overwork with appropriate support.
Cautions & Contraindications
- •Do not use acupuncture in place of emergency assessment for thunderclap headache, neurological deficit, fever with neck stiffness or visual loss.
- •Do not needle deeply or superiorly around the orbit.
- •Do not claim that acupuncture or herbal medicine can cure cluster headache or replace specialist neurological management.
- •Do not use herbal formulas containing restricted or toxic ingredients; verify all prescriptions against Australian TGA requirements.
When to reassess or seek care again
- •Initial: confirm the cluster headache diagnosis against the International Classification of Headache Disorders criteria, including attack duration, frequency and autonomic features.
- •Initial: document attack frequency, duration, pain intensity, side affected and autonomic symptoms, and establish whether the pattern is episodic or chronic.
- •Initial: review neurological assessment, imaging history and current preventive and acute medicines.
- •Ongoing: track attacks with a diary so treatment effects can be judged objectively rather than anecdotally.
- •Ongoing: review whether specialist escalation, including neuromodulation or new preventives, has been considered when attacks remain frequent or severe [1][2].
Frequently Asked Questions
What makes cluster headache different from migraine?+
Cluster attacks are shorter (15 to 180 minutes), extremely severe, strictly one-sided and around the eye, occur in daily bouts, and are accompanied by autonomic features such as eye redness, tearing and nasal congestion on the same side [1][2].
Can acupuncture replace oxygen or triptans during an attack?+
No. High-flow oxygen and triptans are the standard acute treatments. Acupuncture may be used between attacks as adjunctive support, and patients should not delay or replace prescribed attack treatment [1][2].
Which TCM patterns are most common in cluster headache?+
Liver Yang rising with Liver Fire, Wind-Heat harassing the head, and Qi-Blood stasis in the head channels. Long-standing cases may show combined stasis and underlying deficiency.
When should a headache be referred urgently?+
Immediately for thunderclap onset, neurological deficit, fever with neck stiffness, visual loss or reduced consciousness. Promptly for a first attack after age 50, a change in the established pattern, or headaches triggered by coughing, exertion or position change [1][2].
Is acupuncture safe around the eye?+
With conservative depth and angle, yes. Never needle deeply or superiorly near the orbit, avoid infected or broken skin, warn about bruising, and take extra care with anticoagulant therapy.
