I was at a judo tournament and i was on the ground on my back when i tried to push the person off of me with?

with my left leg. Immediatly i felt my knee click like it dislocated so i tapped out and waited for medical help. They just gave me ice because there were';t real paramedics there. My knee if feeling a little better and only really hurts when i bend it certain ways. What is really bothering me is when i walk it feels like there is something in my knee like a pressure kind of. it is hard to explain. can anyone help? they said i might have a little rip in my acl or i might have stretched it. any advice or comments?
