Thanks, Mrs D........do you think a rheumy might arbitrarily attribute fibro to a PN patient, who really doesn't have a family history of pain syndromes- that are not concisely diagnosed?
I mean, if there is some family history, but all illnesses or conditions have been recognized, & treated successfully with no indication of fibro in the past.

I realize that fibro would not have been Dx'd way in the past, as it is not a long-standing recognized affliction/disease/condition.(??)
It seems it is fairly new on the scene and there would be no past history that had been Dx'd as such. It would have to be a determination of a current doc that it had not been recognized, or was thought to be some other condition.(to be considered as hereditary)
As I mentioned, it is not something that can be definitively Dx'd by a blood test
or MRI or CT scan (would it show on a nerve velocity conduction test? If so, it would then be Dx'd by a neuro - wouldn't it?).
It seems it is determined by taking an oral history, putting 2+2 together
and coming up with 5.
From what I've read, many docs don't/didn't recognize it and patients who thought it might be applicable to them, were discounted & treated as if they were 'malingerers'.
