I crouched with my back to a big rock and got stuck inside of it, been trying to get out for the last 15 minutes with no success, help would be greatly appreciated!

EDIT: Never mind, I eventually managed to get out on my own, If you want to know which rock it was I'll provide further information, otherwise there's nothing else for you to do, cheers.
