I checked through the broken bones tag here and searched for broken hand + scar, but my thing is kind of specific. Basically my main character has his hand completely crushed by a large rock, it's magically healed after, but think of it in the sense of say, being healed by modern means. Would there be any kind of scarring or significant visible damage? I'm kinda hoping for something that sticks with him.
Also, just for future reference, I imagine the actual injury would be insanely painful. Would he be likely to pass out from shock?
