Your doctor may immobilize your shoulder in a sling or other device for several weeks following treatment. You should get plenty of rest and ice the sore area 3-4 times a day. After the pain and swelling go down, your doctor will prescribe rehabilitation exercises for you. These help restore your shoulder's range of motion and strengthen your muscles. Rehab may also help you prevent dislocating your shoulder again in the future. You begin by doing gentle muscle toning exercises. Later, you can work up to using weights.
