Why does my shoulder hurt when I raise my arm?

Shoulder pain when lifting your arm can occur for several reasons. One common cause is shoulder impingement, where the shoulder bones press on the tendons or bursa, causing pain. This can sometimes even cause neck pain as well. Another reason could be a rotator cuff tear, where some of the muscles and tendons that rotate your shoulder in place are damaged. The size of the tear can affect how much pain you feel and how much you can move your shoulder.

There are also specific conditions related to other health issues, like diabetes, that can cause shoulder pain. People with diabetes are prone to getting "Frozen Shoulder." This is a condition where the shoulder's range of motion becomes progressively more limited and painful.

If you experience shoulder pain, it is important to talk to a healthcare professional who can help determine the cause and suggest the best treatment plan.
