Visible bleeding is not a typical symptom of a dislocated shoulder, as the injury primarily affects the joint and the surrounding ligaments, not the blood vessels. In contrast, pain, swelling, and instability of the joint are common signs of a dislocated shoulder. These symptoms occur due to the displacement of the shoulder's bones, stretching or tearing of the ligaments, and irritation of the surrounding tissues.
Pain is usually immediate and severe, especially during attempts to move the arm. Swelling can develop as a result of the trauma and inflammation in the joint. The shoulder joint may also feel unstable, as the ball of the upper arm bone (humerus) is no longer properly seated in the socket of the shoulder blade (glenoid).
Dislocated shoulders can also cause muscle spasms and numbness if nerves are affected. While visible bleeding is uncommon, internal bleeding or damage to blood vessels can sometimes occur, especially if the dislocation is severe. Treatment for a dislocated shoulder typically involves resetting the joint (reduction), followed by rest, ice, and rehabilitation exercises to restore function and strength.
