What Causes Pain in the Back of the Shoulder When Moving My Arm?

Pain in the back of your shoulder when moving your arm can have several causes. One common reason is shoulder impingement, where the shoulder muscles get pinched during arm movement. This can sometimes present as neck pain too, as the neck and shoulder are closely connected.

Another possible cause is cervical radiculopathy, which involves nerve problems in the neck that can affect the shoulder. This condition can sometimes be relieved by holding the arm in a certain position, known as the shoulder abduction relief sign.

Additionally, people with diabetes may experience shoulder pain due to various conditions related to diabetes. These conditions can affect how the shoulder moves and feels.

If you are experiencing shoulder pain, it might be helpful to consider these potential causes and discuss them with a healthcare provider to find the best way to address your symptoms.
