cluster headaches
"Have had headaches for over 25 yrs with every doctors going through the same regime of drugs.  Finally got seen by a pain doctor and he immediately asked if any doc had talked to me about Cluster Headache (CH).  NOPE!!!! Started off with 180g of verapimil and Cluster Headaches went from 18 or so a month down to 12. After upping the strength to 240mg I'm now down to 7-9 a month. A complete life changer and glad I stopped seeing a neurologist - my pain doc saved me and could be happier. I rather have 9 CH a month instead of 18"
