seperated and dislocated are two different things. i seperated mine two years ago. it is a 3 or 5 depending who you ask. i was riding in less than a week. i was told i couldn't make it any worse by falling on it, but it would hurt real bad. you prob don't need surgery unless its ur throwing arm and you need it for sports or some shit. otherwise physical therapy will get it back to %100. and the bump don't go away without surgery.
