I realize I am on an old thread but wanted to see if there was any mention of the relationship between FMS and Small Fiber Neuropathy. I have SFN and was dx'ed about a year ago. I now have pain all over and won't go into that. I'm posting here(though I could not find the "New Thread" anywhere and I am a member)because I have recently read that there have been some small studies done on people with FMS and SFN showing that a quite a few also have SFN! Since my dx of SFN, my pain has increased, intensified and spread. I am now wondering if the SFN caused the fibro? Can anyone help me? I have been looking all over this site for more information about SFN, how to treat it, IF my symptoms are fibro and not SFN or a combination of the two. I am really searching for answers and cannot find any because SFN is pretty rare and most drs know very little about it.
