cluster headaches
"Suffered for 4 years in a row from a very strong cluster headache, the doctors prescribed all sorts of medications, from migraine medications to steroids based medications, until I met a brilliant neurologist, who successfully diagnosed my case as Cluster Headache, and after 2 month using Verapamil   the headache disappeared for 3 consecutive years, I still suffer from mild attacks every now and then, but it is not comparable in intensity and frequency with my previous state, in brief, Verapamil is magical in healing cluster headache,"
