I know this question may sound a little crazy but I have had two rhuemys tell me that fm and cfs are one in the same. They both said that people that have one of them most of the time have the other. Is this true for most of you? Then I had another doc tell me that they were different and not the same at all!! These doctors seem to all have different opinions. I am just a woman trying to figure out what is wrong with me and I just wonder if the new retrovirus is in fm patients as much as cfs patients. I would appreciate any input you can give me about this subject. I think we are the only ones that really know what we feel. The docs seem to be playing a guessing game with me. take care and God bless to all of you, Faith I finally think we are finding our common ground with the xmrv. Maybe there is hope after all.
