I have been having knee troubles since mid november of last year. The pain came up about two weeks after basketball had started and it hasn't gotten much better or worse to this day. The pain comes when I jump, squat, lunge, etc. which causes playing basketkball very difficult. The pain is worst directly on my kneecap. I went to the doctor about it in March and they really didn't tell much except to ice it and take ibuprofen which I have been doing often for the past 2 months with very little activity on it. That didn't really help too much so I decided to start working out on it doing some light jump exercises on it, too maybe strengthen the muscles. I did those this past Monday and Wednesday, and on Thursday my knee had swollen up and had a big bruise just above the kneecap and is painful. I don't know what to do to heal it. If you could please give me some advice to heal it, it would be greatly appreciated. Or maybe some exercises to do to prevent it in the other knee. Thank you
