At night I get burning pains and tingling in my shoulders and elbows running down to my hands. When the pain is at its worst I get very sweaty, and wake up feeling drained and headachey as if I have flu or a hangover. When I wake up my shoulders are tensed right up and my fists clenched. The pains seem to be made worse if I use the computer for more than half an hour, or if I knit. As I am a video maker with a love of Icelandic knitting, this is affecting my quality of life quite badly. Medics seem mildly puzzled / disinterested so far. It started about 8 years ago and is getting steadily worse. Behçet's thing do you reckon, or something else?
