A few years back, after a boxing session I sat on the floor, crossed my (straight) legs (right over left) and it felt like something ‘popped’ at the back of my left knee. Felt like a tube of cold water had split. And then I couldn’t walk, or even get to my feet, for about 4 hours.
Bizarrely, after getting a cab directly to hospital and waiting for an hour, I could walk fine, like nothing had happened. This was about 5 or 6 hours later. But obvs something did happen. Still puzzles me and was wondering if anyone else has had anything like this before?
