Eliminate Shoulder Pain
Bursitis of the shoulder occurs when there is swelling and redness between the top of the arm bone (e.g., humerus) and the tip of the shoulder (e.g., acromion). Between these bones lie the tendons of the rotator cuff and a fluid-filled sac (e.g., the bursa) that protects the tendons. Normally, the tendons slide effortlessly within this space. In some people, this space becomes too narrow for normal motion. This causes irritation to the tendons and bursa, which become inflamed. Inflammation causes the tendons and bursa to swell, making the space for movement still smaller. Eventually, this space becomes too narrow for the tendons and the bursa—and every time they move, they are pinched between the bones.
