Yesterday, I was in a squat looking through a cupboard. When I got up, I felt as if my knee came out of place. (This has happened to me in the past, less often then often). Now, I can usually kick my leg out & it will snap back. This time I couldn t. Almost as if it was too far apart. I had someone pull it back in place. Now my leg is sore for 24 hrs. Prior times, it would go away quickly.
