once i likely came close to dislocating my left shin while getting up after sitting cross-legged in my room for about an hour. i say likely because i can't say there isn't room for doubt, but as i was attempting to stand, i felt something come loose in my knee along the left side. i immediately lifted my leg enough to where it wasn't bearing weigh (using my left arm to hold on to the bed so i wouldn't lose my balance), and it definitely felt as though my shin was sitting on the edge of the socket, jerking back into place seconds later. that was not fun.
