I don't know which is which. I have MG, and have been told I have seronegative Rheumatoid Arthritis, my esr sed is 50, This is my symptoms, and I am thinking these are a little of both, so I would appreciate anyone who has both and what their symptoms are. I get such pain in my elbow, shoulders fingers well and can't move , toes, knees even the soles of my feet, it gets so bad I can't move my arms, the pain is a 10, in the morning it is a little better but stiff but by evening it is horrific. I am trying to get in with a rheumatologist....hard to find where I am . Please any advice?
