Had plica surgery a year ago. Fell 6 months ago. Used the elliptical machine on Thursday night. Friday I was fine. Saturday very painful, no noticable swelling. Had done a lot of going up and down stairs. Sunday I used the knee brace and did limited walking and no stairs. Today I used the knee brace again and limited the bending of my knee. I did use ice. There is slight swelling on the lower, inner portion of my knee, but you have to be looking for it. Slight improvement. GP pressed on the area with the slight swelling. Extremely painful. He says bursitis. Which would be your guess? Aches even at rest. Thanks.
