I injured my knee years ago playing soccer, I was running full out when my right foot met with the ball at exact same time as the other person, my right leg stopped dead and the rest of my body carried on the motion, my knee twisted alot, I never really went to go get it checked out, after that, I can now twist my foot around to almost 180 degrees, I also have a loss of feeling in the skin on my knee cap. I was in a car accident early last year, and the same knee took all the force of the crash, I again refused to get it checked out but it is started to become unbearable pain daily. My knee gives out on a constant basis and some days I have to limp to be able to get around. Any idea as to what the issue would be as I do not have insurance.
