Dislocated shoulder

my clavicle is cushioned by my rotator cuff and I have a full thickness labrum tear. My understanding is the shoulder is held in place by surrounding ligaments. My left arm is basically useless right now and it is my dominant arm. Cant sleep either I have a habit of sleeping on my arm and it doen't seem to like that very much. =)

Does it hurt to do things like grab milk from fridge or brush teeth, reach up etc? If so you might want to go have it looked at.
