It also could be a SMALL FIBER NEUROPATHY<, dont blame everything on Fibro,, talk to a Neuro and ask about a skin biopy test,,, (punch Biopsy),, my arms burn all the time,, my fingers and hands burn,, and it was chalkedup to fibro till a punch biopsy showed reduced nerve fibers,,, does he feel like hes burning ,, do his legs feel cold for no reason,, or feelings like water running down his leg when there is none,,, again,, dont let them blame it all on fibro
