Once the shoulder is dislocated out of its socket, it is usually unstable. The joint can become loose and the shoulder can often slip out of the socket. The causes are the initial dislocation as well as repetitive strain on the shoulder joint from activities that typically overuse the shoulder such as swimming or tennis. Symptoms include shoulder pain, repeated dislocations and feelings of the shoulder “giving out”.
The key for treatment is strengthening the shoulder muscles and working on shoulder control to increase stability.
