If you have a frozen shoulder, then you understand how frustrating the pain and limited mobility in your shoulder and arm can be. It may seem almost impossible to accomplish simple tasks like dressing and bathing. A frozen shoulder seems to come from nowhere. Often there is little or no injury, and there are really no specific shoulder tests to determine if you have a frozen shoulder. The sign of a frozen shoulder is easy to spot: limited, painful range of motion (ROM) in your shoulder.
