@trjonas Thank you for your response. I'm glad you had a pathway that had clearer indications and a positive result. For me, MRI's and other scans have all been clear or "clear enough" might be more accurate because I do have various findings on my neck such as foraminal narrowing and some bulging. That said, I've always wondered about compression, and given what you passed along from your doc about no imaging being able to show the damage, I still wonder about it. I have also read studies that seemed relevant, as does your case.
I've mentioned compression to many docs over the years but none really seemed to indicate it was on their radar as something they were familiar with, or not relevant for me given the other symptoms and imaging. Too much seems to be unknown about the pathophysiology and the nature of the beast... I did just have a occipital block recently, which is on the CH "treatment pathway" with my current neurology doc. It did have a bit of benefit for a couple days.
I've tried the long list of meds and blocks over there years, and a long list of specialists, without much benefit. I do think the CCH is part of the picture. Is there also, nerve compression, or cervicalgia? Maybe... Hemicrania Continua has also come up in my treatment because I have very high baseline headaches in addition to attacks (and other CCH symptoms like the knot in my neck, rhino/sinus and eye swelling, etc). One odd thing that does seem uncommon is that I have a lot of nausea, as if the vagus nerve is somehow getting crosstalk or something (who knows really - that's just my imagination trying to peer inside my head :)) Maybe I'll start a new thread asking the community about nausea...
All that said, I am grateful to have some new options thanks to this community. I wish I had found this sooner! For now, it seems busting and D3 are the way to go. RC seeds on the way as a quick way to start. I'll be watching for your updates as well - fingers crossed for good results for all.
Thanks, L
