Yeah i have messed up shoulder sockets aswell. Its better not to rough it apparently. I saw a doctor about it after they had popped out a few times. She told me what happens is the "cart-ledge" in your shoulder that holds your arm in your socket gets messed up and if it isn't properly fixed ( i.e. either surgery or lots and lots of physio to build the muscles around the socket) your arm rolls around inside your socket and just wears the "cart-ledge" down further and further till it eventually gets to the point where if you bump into something, your shoulder comes out, just like that. But yeah I'm roughing it too, so far I've been more or less fine.
* I just read that last post, sounds like if your going to pop your shoulder out, thats the way you want to be doing it. Kudos drunken robot man. :lol:
