A shoulder dislocation occurs when the upper arm bone (humerus) pops out of the shoulder socket. This often happens due to a fall, sports injury, or trauma. Symptoms include intense pain, swelling, and an obvious deformity in the shoulder area. Treatment typically involves reducing the dislocation by maneuvering the bone back into place, followed by immobilization with a sling and physical therapy to regain strength and flexibility. In some cases, surgery may be necessary to repair damaged tissues and prevent recurrent dislocations.
