About Shoulder Tendonitis

Tendonitis of your shoulder is an inflammation of your rotator cuff or biceps tendon. Your rotator cuff consists of the muscles and tendons in your shoulder. They connect your upper arm bone to your shoulder blade.

Your injury may range from mild inflammation to severe inflammation of most of your rotator cuff. When your rotator cuff tendon becomes inflamed and thickened, it is also called rotator cuff tendonitis. Your rotator cuff tendon may get trapped under the roof, or highest point, of your shoulder. This is called your acromion. It is formed by a part of your shoulder blade, called your scapula.

The following are the most common symptoms of shoulder tendonitis. However, you may experience symptoms differently. Symptoms may include:
