I'm a professional basketball player so my knees are very important to me. Six months ago I had surgery to repair a small meniscul tear in my right knee. I rehabbed aggressively and proceeded to play approximately 6 weeks later. Things went well for the next two weeks and then I started to experience swelling around my knee. No pain, only swelling. After the season I took 5 weeks off like my doctor said, no activity whatsoever, only walking. I slowly started to ease my way back into playing, weight lifting to strengthen the muscles and running. The first two weeks were fantastic, no swelling. I took a day off and woke up the next day with swelling, for no reason. I also experience a popping, cracking sensation occasionally that is a little bit painful. The doctors can't tell me what is wrong. I'm 26 and extremely frustrated. Can someone please help me? I will do anything to have a healthy knee... Thanks so much!
