Omg I'd do anything for some oxygen when im in a cluster! Unfortunately Massachusetts only allows o2 for o2 deprivation therapy
. I try to make sure I'm breathing properly taking full breathes as when I'm having a CH my breathing gets very shallow n slow(does that happen to you guys too?) I'll chug coffee soon as i feel one coming on and take bayer migraine, the caffeine helps constrict the blood vessels in your head, of course sometimes i throw every thing up soon after from the pain but often not. I've been told lidocaine in a nasal spray works amazing, I've looked it up before but can't remember the name of it, odd thing is even tho i told my dr the name of it she can't find it in her database so can't prescribe it to me. I find squeezing my head as hard as i can, pulling my hair till I'm just about pulling it out, pushing in hard on my right eye, and pressing on all my pressure points on my head really helps, if you aren't familiar with them look them up as they really help. I'll also bite my arms just about to the point of drawing blood distracts me from the brain pain.
