The shoulder is the most often dislocated joint in the body due to its mobility. Dislocation occurs when the head of the humerus is dislocated from its socket. Symptoms and signs of a shoulder dislocation include nausea and vomiting, lightheadedness, weakness, and sweating. There are various methods of reducing a dislocation and returning the humeral head to its normal place.
