I got an injury a year ago from roller blading. I soon ended up spraining my MCL and tearing my ligament in my left knee. I needed to wear a brace on it for the entire summer! (Big bummer) and I finally could stop wearing it when I started going to school again. But now it is almost the end of the school year and the knee pain is starting to return in my ligament but not in my MCl. The pain is not always consistent but it starts to throb when I kneel, bend down, or do anything that involves bending my knee. I don't know what is going on with my knee and it is concerning me because the pain is starting to return.
