Reading posts here, and a question arose for me. My old MD said I had RA, although all he had was my achy osteo bones and the RA factor and some nodules that comes from OA, not RA. Did any of you have a positive RA factor due to inflammation- not Rheumatoid related? I think some MD's can misdiagnose easily because of that factor. I was put on RA meds, got more sick, more flue like feeling. After 6 months I stopped taking my meds since I never improved, but only felt more flue-ish. Got more energy, and no more aches in my joints than normal. I am sure I don't have RA since I never had any joint swelling. My constant feeling of having a flue points to something else. New doc. checked for Lyme and B12, both negative. Other values seem normal. Are there any labs that tend to be abnormal in chronic fatigue? Any input would be appreciated!
