I have tried everything including off-label surgery, that's one I have not. Thanks.
Also, you might be familiar that taking pure oxygen during an attack in known to stop the attack. The problem is that it builds a tolerance were you need more and more which brings problems of its own.
They tried it based on some published research. Here's one such study. https://n.neurology.org/content/66/12/1920
Also, on a possibly constructive note, have you investigated mycotoxins or heavy-metals (as a possible cause)?
Wow! Jeez, I mean the thought of doing that myself has certainly crossed my mind in semi-jest, mid attack, but nope.
I found this old study [0] and based on that I had endoscopic sinus surgery. It stopped a 9 month cluster and I did not have another attack for almost a year. The surgeon did it because my sinuses were opaque, but the reason I did it was with the hope of the chance of cluster benefit.
Are there any foods or drinks that bring it on or make it worse or better? Sorry if it's a dumb question, I'm just curious!
There is an instant solution to stop the pain, it’s in that study as a footnote I believe. But it’s illegal, extremely habit forming, and very expensive.
I have heard that there is a new novocaine nasal spray coming out. That should do the trick if I can ever get my hands on it.
