I was just diagnosed with sero negative RA last week after months of tests trying to figure out why I keep getting sick. I also am a carrier for MRSA which has made me think that this could be more of an infectious arthritis than RA. But I don't have a fever and am experiencing a typical RA pattern. Is there anyone else out there who has both of these conditions? The rheumatologist started me on prednisone and plaxenil but I actually feel worse. I thought the prednisone would make me feel great instantly. I'd love to hear from anyone who has experienced anything similiar.
