What is Rotator Cuff Injuries?

The rotator cuff is a powerful team of muscles and connecting tendons. These muscles and tendons attach your upper arm to your shoulder blade. Your rotator cuff helps you reach, throw, push, pull, and lift. Without it, your shoulder would be nearly useless. Rotator cuff tendons can become damaged or inflamed in many ways. These include irritation (overuse), pinching (impingement), calcium deposits (calcification), and splitting (tears). Any of these conditions can make you shoulder weak, tender and painful.
