From Wikipedia, the free encyclopedia

Chronic paroxysmal hemicrania (CPH), also known as Sjaastad syndrome, is a cluster-like headache. It normally consists of multiple severe yet short headache attacks. These attacks normally will only affect one side of the cranium, hence the term hemicrania. It is more common in females than males. CPH headaches are treated with non-steroidal anti-inflammatory drugs, in particular indomethacin, which is usually totally effective in eliminating the symptoms.
