Frozen shoulder is stiffness, pain, and trouble moving your shoulder. It may happen after an injury or overuse, or from a disease such as diabetes or a stroke. You may have pain that keeps you from using your shoulder. However, you need to move your shoulder. If you do not move it, it will get more stiff and sore. Your doctor may order an X-ray to make sure there is not another cause for your stiff shoulder.
You can treat frozen shoulder with heat, stretching, over-the-counter pain medicines, and physical therapy. Your doctor also may inject medicine into your shoulder to reduce pain and swelling. It can take a year or more to get better. Surgery is almost never needed.
