....are you female...some behind the times pcp's don't think women get CH...they are frightfully and obviously wrong.
...what's your diagnosis? triptans were developed for migraine (but work for CH too)...is this his hang up?
...i am not recalling the name of standard reference that physicians use...hoping another clusterhead will come along and provide. it says the same as the below .orgs and .gov (not the frequently derided .coms)....i could have filled a page easily. EVERY ONE of them states the standard acute care for CH abort is OXYGEN and TRIPTANS (Imitrex)...
....if there is a way to present this info to your pcp...mail or email or mychart or advocate w/o being present to witness the embarrassment (and therefore reluctance to believe) i would try that. if you have an honest relationship where you can sit and talk openly face to face and present references...go for that (i'm suspecting no...but that's an assumption)....
....i saved this comment til last but i was SHOUTING it upon first reading your post..."get thee a new doc"....sheesh, this is a bizarre thing for him to say. preferably a headache specialist (or at least a pcp willing to listen, learn and provide)....and not just any neuro (who frequently know jack spit about CH)....
