For the last several months, I have had these symptoms that have gotten progressively worse. My hands, feet, and ankles swell (elevating my feet doesn t help). My right shoulder, elbow, wrists and hands (right and left) with a knot on the top of my right hand have terrible pain. I cannot raise my right arm more than midway, due to the pain. The joints in my wrists and fingers is very bad. Also my knees swell, and ankles and feet. Joint pain is very bad in knees (can barely get up from a sitting position, as knees feel as if they are tearing apart at the joint. My ankles hurt and swell, making it difficult to walk and keep balance, and joint pain even in the joints of my toes. Is this Rheumatoid Arthritis? How do I regain my mobility? What treatments are available? Thank you.
