Guys, I went snowboarding today and I took a nose dive into powder and the momentum threw me sideways and I twisted my knee and I don't know what is wrong. My knee hurts like crazy every time I move it and I'm having problems sitting and standing, but if i sit then the pain goes away if I don't move and same goes for standing. I think I pulled my MCL but aren't sure. I also didn't hear a pop when it happened. Does anybody know what I did to my knee without going to the doctors? Thanks in Advance
