Almost every joint, at one time or other. They seem to make the rounds. First was toes, ankles and knees, then shoulders and arm pain, Now it's in my neck, and hips mostly. I had rapid unexplained weight loss with my first episode, along with leg pain and even swollen toes. Sometimes the wrists will be involved. Lab results confirmed the diagnosis. Prednisone really helps and I try to limit it, probably too much. I would feel better if I took more.
