Last Friday (five days ago) I was doing a lunge when all of a sudden I felt a pain in my right knee. After fourty five minutes of thinking it was just a soreness I realised I did something really bad to my knee. It was the worst pain i ever experienced. At first I thought it was my meniscus becuase that was the only thing that was hurting now my patella and my meniscus are killing me. I can walk on it but it kills to go up the staris and get out of a chair. Ever since Friday I have regiously iced my knee my knee swelled up and is still really painful. My gym teacher and athletic believe it is a strained patella but I have iced my knee for 5 days and they even said their would have been less swelling if it was that. My best friend tore her acl almost two years ago and even though I know it is not an acl tear she think I did something a lot worse (than syrain my patella) to my knee. I am going to the doctor on friday becuase I think there is something really wrong what can I do or should I do in the mean time and it is woth it to go to a doctor.
