Okay so yesterday I go to judo and I pop some thows, I get thrown and work some ground. Everything is nice but I notice a slight pain in my knee when I turned my foot towards the interior. It all went fine until this morning. I had to run for the train. I got there in time I sat down and when I got up 40 minutes later my left foot wouldn't straighten all the way out. The knee became "contracted" so to speak. The bastard knee didn't allow me to bend my foot all the way. So I thought it's temporary. Now the knee is getting a lot of stiffer and I have to walk around with a bent foot like a retard!!! Wow!!! This is freaking me out. I feel like it's swollen a bit on the inside but it's stiff like a fucker and doesn't like to bend that much. Could this be serious shit? Torn ligaments and surgery? Or just some sort of knee spain? I have to say that I experience no physical pain but the fucker doen't work normally. Anyone know what's going on? Thanks in advance.
