My knee popped in class tonight. It wasn't from a leg lock, I think I just twisted my leg awkwardly. The thing is, it isn't swollen or anything and it doesn't feel any differently (ie, no pain). However, I think I've heard people say before that knee poppage = cartilage tearing. For those of you who have popped your knee, did it end up being damaged? And when it happened was it painful? Is this an indication of an (x)CL tear? I know I'll get the inevitable "go see a doctor, why are you asking medical advise on a forum". Well, I've already had a ton of doctor visits in the past year, and I don't think I have the money to see a doctor and get an MRI. I've had an MRI before and it cost 1000 dollars. I don't have that kind of money right now, so if I do end up having to go to a doctor, I want to be sure as possible that something is wrong with my knee. Should I be worried?
