I have a chronic form of cluster or hypnic headaches. Basically everytime i go to sleep i wake up with a headache. When it started 12 years ago it was more the severe form that usualy comes with cluster headaches , but it quickly became like a chronic dull type tension headache form. I've tried many medications to prevent them over the years but never tried verapamil. a lot of medications loose there eficacy over time or has too much side effects. Ive tried botox 2 months ago but havent notice any change at all. My neuro is open to me trying emgality to see if i get any relief from it. Anybody here had long time relief with short rounds of prednisone ? i havent tried verapamil yet, will talk about it to my neurologist. Thank you
