I dislocated my shoulder. which exercises can i do to stop the pain?

Depends: The pain from your first dislocation should start to abate fairly rapidly. Usually within a 1-2 weeks people are feeling much better. If this is a chronic condition... Multiple recurrent dislocations, then the joint is "upset" because it remains loose. Most strengthening exercises and stretching exercises can be performed, as long as the shoulder does not feel like it wants to pop out again.

Exercise w/ caution: Dislocations occur from trauma and/or laxity of the shoulder capsule and ligaments. Prolotherapy or platelet rich plasma injections can help strengthen the tissue. Exercise will strengthen the surrounding muscles but not the lax tissues.

Safe exercises: For an anterior dislocation after a few days of rest and immobilization start with pendulum exercises and shrugs. Over the next few weeks increase the range of motion. Use a broomstick held in front of the body and move it side to side then upwards to the shoulder level and finally overhead. Always avoid positions that reproduce the sense of instability. Next, start gradual resistance exercises.

See doc first: A dislocation can result in a fracture, labral (cartilage) tear, capsular tear or a rotator cuff tear. Recovery may or may not initially include exercises, depending on the cause of your pain. See your ortho doctor for further evaluation.
