All interesting !! I've just started my 7th episodic CH cycle. I get every 2 years like clockwork. 6 weeks to 20 weeks. I have tried many things. I completely quit drinking, and managed to skip a cycle. Well .. here I am with another failed hope. At least I'm 4 years sober, and off all the narcotics I was doing on my downward CH depression spiral.
Here is what works for me: O2 is always my best cure!!!
Once I feel it coming on. (Eyeball pain, then temple, then jaw, then left side of neck) Starts mild, but I normally have about 20 minutes before I'm in full blown can't bare it pain attack.
I rub Vicks vapor rub on the temple, jaw, and neck. Then 15 ppm oxygen. Boom!! Within 5 or 10 minutes. It stops. Most times before I am in the unbearable part. I don't know why, but the Vicks works great!! Even by itself sometimes. Very hot, warm wet towel over the affected side works also over the Vicks. Sometimes O2 isn't available, so I have learned these neat other busts. Especially from these forums. Sumatriptan shot works great, but really shouldn't use more than 3 times a week, and have extended my cycles if I do use it alot. Varapamil 3 times a day for a few weeks has still won for my shortest cycle period.
I hope this helps someone. I really didn't understand why the Vapor rub works, but after reading this discussion bout the histamine stuff, maybe there is something to it. Who knows. I have never been down so many rabbit holes about anything in my life like I have with the CH. The how, what, and why's. I appreciate you all, and sympathize with you all. It's a brutal disease. We all gotta live with it, and there are ways to cope. Ya just gotta find what works for you I think. It can be managed, ya just gotta believe it!! Life is good!!!
