Hi! About a week ago I was playing a game and the ball had went under the garage door which was half way open so I bent down underneath it and my left leg was planted and my body was shifting so my leg had twisted sideways and I heard 2 popping sounds. It hurt really bad afterwards and couldn t put pressure on it for about a couple minutes. And after that I thought it was better until I went to turn around and my pain came back. There is no swelling or any other symptoms just when I twist my knee it hurts. And the next day the back of my knee was in pain/ sore. I made an appt for tomorrow. Any idea of what it could be?
