A few months ago I was working and i squatted down to scan something and on my right knee on the right side it felt like something was tearing, it was a sharp burning sensation. The next day a very large bruise showed up. I though nothing of it. However I started to get pain in that knee for no reason, and it really hurt. The pain would last all day unless i took something. But it only happened maybe once or twice a month. Now my knee hurts almost all the way around and down into the leg, and putting it into an immobilizer is the only thing that seems to make it feel better. HELP ME PLEASE !!!!!!
