I have a history of Hepatitis C and was treated and cured. I still have a damaged liver and had a TIPS procedure last year. I have bleeding polyps in my stomach and the Doctors moniter me closely. I see a Hematologist for Anemia and have to have iron infusions. I am now having knee pain for 8months. It comes and goes, but is serverly painful. I can t even stand at times. My Doctors can t dx it. Could I have an autoimmune disease? I ve been tested for Rheumatoid Arthritis s it came out positive once and just recently negative. Any suggestions would be gratefully appreciated. Thank you.
