Have they tested you for MRSA? My brother-in-law had pain, swelling. and warmth in his total knee replacement for 5 years after his surgery. He was told that he just needed to learn to live with it. He finally got a second opinion. The new doctor drew off some fluid from the knee and determined that he had MRSA.

He had the knee replacement removed and replaced with a temporary knee. After a month of antibiotics, the MRSA was gone. He then went on to have a new knee replacement. He was back in the tennis court 2 weeks later.
