question: About 2 months ago I was painting the woodwork in one of the rooms of my home, naturally I was on my knees getting up and down. After that my knee swelled up and it became painful to move it. Going up and down steps was the worst. Went to the doctor and she saw water on the knee and gave me medication to reduce the swelling. She also sent me for a ct scan which showed tendinitis. The swelling did go down but now I notice the bone on my knee is protruding and hurts if I kneel. What could be the problem. Should I go back on the anti-inflammatory?
