Hi, I was diagnosted with osteor in January of 2017, I have symptoms and the RA doctor that I see claims that I need to see a Dermatologist for the rashes I get around my joints. The Derm concluded that I also have excema in the legs and forehead. I get joint discomfort in the spine, legs, elbows, hands,knees and forehead, But lately I also get soreness in the ribs and shoulder blades, is this common?
