A separated shoulder is an injury to the ligaments that hold your collarbone (clavicle) to your shoulder blade. In a mild separated shoulder, the ligaments might just be stretched. In severe injuries, ligaments might be torn.
In most people, a separated shoulder doesn't usually require surgery. Instead, conservative treatment — such as rest, ice and pain relievers — is often enough to relieve the pain. Most people regain full shoulder function within a few weeks after having a separated shoulder.
