So on Friday night I was playing hockey and I got hit, my left knee got twisted up and I heard a pop and it felt like something got displaced, and got back into place. I've had problems with my right knee with patellar subluxiation, so I know what that feels like. This most definitely did not feel like that. There was some pain, but not a lot. I got up off the ice and skated off (I couldn't put much weight on it, so it was kind of a push and glide kind of thing). Anyways got off and it's now Sunday night and I haven't gone in yet, was planning on going in tomorrow. There was immediate swelling, although not a lot. I have been walking around on it with a good limp since mid day Saturday. It is very unstable though. I when I walk in a straight line it's ok, not normal but ok. But if I make a turn (not even sharp just like walking in a circle) I feel like it will give out. In fact I was walking around a corner and it did give out towards the inside of the knee. I have had problems with range of motion, although I think it is due to swelling. Swelling by the way has come up quite a bit today. I've been reading up on acl injuries, and I honestly think that's what it sounds like, but also the giving way to the inside leads me to think maybe I damages my mcl as well. My dad also said that my meniscus could be damaged so now of course I am very worried about a blown knee. When you blow out your knee is there always a lot of pain? I have a pretty high pain threshold, and I would say pain was a 5 or 6 out of 10. I just want to know what to expect when I go in to have it looked at. Is there good chance based on my symptoms of having a blown knee? Thanks for reading and if you choose to do so, replying. I appreciate it.
