I suffer from something my Doctor calls "Cluster Headaches", they occur annually and normally for a period of between eight and twelve weeks in my case.
The Doctor has tried a couple of the so called preventative medications that seem only to send my head into orbit (totally stoned!!), but nothing else.
This year, for the first time, she has prescribed Oxygen (something about 100%/15/10) that is used at headache onset. It works
as soon as the headaches start I put the mask on and 10 to 15 minutes later the pain starts to subside.
My question is how? I have searched google and found no explanation, I know WHAT it does, but no details on chemical/physical reactions. Any Doctors or Nurses here?
