What is Rotator Cuff Syndrome?

Your rotator cuff is a very powerful team of muscles and connecting tendons that attach your upper arm to your shoulder blade. The rotator cuff helps you reach, throw, push, pull, and lift. The pain occurs when the tendons in your rotator cuff are swollen. There are several things that can cause this area to hurt if you fall on your shoulder, or lifting and reaching too much, or if you threw too many pitches. 

Symptoms

• Pain when you bend the arm and rotate it outwards against resistance. 
• Pain on the outside of the shoulder possibly radiating down into the arm. 
• Pain in the shoulder, which is worse at night. 
• Stiffness in the shoulder joint.
