In some cases nerve damage at the time of the original injury may be the cause of the frozen shoulder.

There may be a separate problem going on altogether. For example, neck arthritis with nerve impingement can cause shoulder pain and weakness. Loss of motion leading to a "stuck" or "frozen" shoulder can occur.

Many rotator cuff tears occur gradually. Often there's been a history of shoulder problems. Painful motion, night pain, and gradual weakness in the arm may result in wasting of some of the muscles. Given these conditions, a frozen shoulder can occur. This is especially true if the patient hasn't had a good rehab program after the repair.

Physical therapy to restore motion and function is the first step. If your symptoms aren't improved in six to eight weeks, then a second shoulder surgery may be needed.
