I had surgery to repair a shattered wrist; after the cast came off, the surgeon said he'd follow up in 3 months to start physio, but in the mean time as much as it hurts, I can't break it by stretching.

So I spent every waking moment looking for motions that I used to be able to do but which hurt when I started to do them, and slowly working those motions despite the pain.

At the followup to start physio, the surgeon did a quick range of motion check. His jaw literally dropped when I demonstrated that I had recovered 95% range of motion without pain, full flexibility. “You… don't have to come back.”
