Cluster Headaches
"Had clusters 37 years now. I&#039;ve tried literally EVERYTHING out there. The only thing that works for immediate relief is imitrex injections. If med takes too long (nasal or pill), it simply doesn&#039;t work. Gabapentin (sp) regime should be started immediately, they eventually stop the nerve from spasms. Imitrex is now available generic (sumatriptan), however, still expensive. I pay $75/shot only available as a two-pack."
