A common cause of shoulder problems is pain of the tendon, a cord that attaches to the muscle or the rotator cuff, which helps with circular motion.
A sac of fluid under the highest part of the shoulder is called the Subacromial Bursa. After completing activities such as painting, playing a sport or lifting something you may have soreness.
The joint socket is shallow, which allows a wide range of motion in the arm. The main joint in the shoulder itself is formed by the shoulder blade and arm bone. The rotator cuff keeps the shoulder steady as the arm moves and is made up of four muscles that surround the arm.
