Shoulder pain includes any pain that arises in or around your shoulder. Shoulder pain may originate in the joint itself, or from any of the many surrounding muscles, ligaments or tendons. Shoulder pain usually worsens with activities or movement of your arm or shoulder. Certain diseases and conditions affecting structures in your chest or abdomen, such as heart disease or gallbladder disease, also may cause shoulder pain. Shoulder pain that arises from some other structure is called “referred pain.” Referred shoulder pain usually doesn’t worsen when you move your shoulder. Referred pain to the shoulder can also be caused by neck injuries and can be diagnosed and treated by utilizing shoulder injections and nerve blocks in the neck region that can help determine the source of the pain and provide a long-term treatment option.
