Chronic Paroxysmal Hemicrania (CPH)
Location and symptoms
A variant of cluster headache, however shorter in duration but more frequent, from 6 up to 20 attacks per day. While for cluster headaches men are more affected, it is women who are more affected by CPH.
See cluster headache.
Frequent daily episodes of CPH almost always respond to the use of 25-50mg of indomethacin taken three times daily.
