Grandma, I am so sorry to hear of all your immune difficulties. I can't take any meds at all for my fibromyalgia as they kill off my white blood cells, and as I've had cancer once, I definitely don't want it again. So I see a homeopath, who is brilliant. Doesn't cure the fibromyalgia but helps greatly.
Baggs, I know what you mean about diagnosis. It was at least ten years before I was officially diagnosed, and then it was by my chiropractor! He sent me to my gp who said "oh yes, it probably is!". I've probably had fibromyalgia for over 25 years now, and sometimes I despair of the NHS. They can be so wonderful with so many things, but fibromyalgia isn't one of them.
Annep - oh dear, an expensive lesson.
