I keep wondering about this question, is RSD a form of fibromyalgia? I have seen a neurosurgeon three times in the last year (he is very brilliant and has written and published numerous books) since I was diagnosed with RSD. This surgeon has said several times that he is certain RSD and Fibro are strongly linked. One other neurologist in Chicago indicated he felt the same way. However, none of my other doctors have ever mentioned this connection (including Cleveland Clinic). I know last year I read numerous books on chronic pain and I recall one author stating a person can't have RSD without having Fibro but I can't recall the book or author. Does anyone know if there may be a link of some sort?
