This is an interesting thread... I have large fiber PN, lumbar problems, autonomic issues, but have been suggested by several neueros that I have fibro... I was sent to the hot shot rhuemy around here - who - while looking closely at other things and taking more blood at one time then I thought was possible for tests - poopooed the whole fibromyalgia question and said in his profession they referred to it as the "f" word literally (his words) - and didnt believe in it.... and that it was referred pain from other nerves/musles not working right (mainly for me in my back and the back was what needed to be dealth with)... anyone run into this? Is this supposed to be secondary to PN, etc.???? Cause the fatique side of PN, which I know I push to the limit every day - never seems to let up, or the aches.... ?????? Are there quantative tests???????? Or something or help this?
