How to spot the symptoms of a cluster headache
Cluster headache affects up to four in 1,000 people - similar to the incidence of multiple sclerosis and Parkinson's disease.
It is relatively unknown but, unlike migraine, it mainly affects men.
On average, it takes six years to obtain the correct diagnosis and appropriate treatment, resulting in untold misery and possible devastation for those affected.
The European Headache Federation (EHF) and the European Headache Alliance (EHA) are now working together to educate and to raise awareness of the impact and burden of this disorder through the 'What's under the hat?' public awareness campaign.
The first Cluster Headache Day will be held on March 21.
The word 'cluster' refers to a period of time lasting weeks or months, with an increased number of headache attacks associated with seasonal changes and light hours in the day, peaking at the equinox. Often people feel restless and agitated during an attack because the pain is so intense, and may react by rocking, pacing or banging their head against the wall. Symptoms include:
* a red and watering eye
* drooping and swelling of one eyelid
* a smaller pupil in one eye
* a sweaty face
* blocked or runny nostril
* a red ear
