Well, after reading the article. (Too many big words for 4:30 in the morning by the way. ) I can honestly say I am not really sure. There are so many illnesses that sound similar nowadays that I am sure some are actually the same thing under different names. I know that depending on the discipline of certain docs, FM can be called different things. A Rheumy can call it FM, a pain doc calls it something else, a neuro calls it neuralgia, etc., etc., etc. You get the point.
So while I am not sue if FM is RSD or a version of it...I can't say. You may want to talk to the gals (and guys if there are any) at the RSD forum here and see what they have to say!
