Cluster Headaches

Cluster headaches begin unexpectedly. They're much more painful than migraines or any other type of headache.

They're called cluster headaches because sufferers usually get one to three of these attacks every day, for several weeks or months, before they subside. A pain-free period will follow, which sometimes lasts months or years, before the headache attacks start again.

Organisations such as Ouch UK offer advice and support.
