However, I have two questions:
1) (I doubt this is possible, but I'm not sure, so I'll give it a shot) Is is possible for one to pop his dislocated shoulder back into place by himself, or using the help of some sort of inanimate object (like a tree, wall, table, whatever)? Once more, I doubt it, but I want to be sure. My character's shoulder gets dislocated, and he's by himself, in a big prison cell. Anything he can do in any way to make it hurt less? Time period is around 130 years ago.
and 2) What happens if the shoulder is not popped back into place? I'm assuming tons of pain, etc, but I want more factual details.
