A dislocated shoulder occurs when the arm bone pops out of the shoulder socket, usually due to a fall or trauma. This injury is common in football, hockey, rugby, soccer, skiing, and other sports. If you have a dislocated shoulder, see your doctor immediately. He or she can correct the dislocation. Afterward, you will be given instructions for home care, such as ice therapy, using a sling, and taking pain relievers.
