The rotator cuff is a group of four muscles that helps to lift your shoulder up over your head and also rotate it toward and away from your body. Unfortunately, this group of muscles is frequently injured by tears, tendonitis, impingement, bursitis, and strains.

Rotator cuff syndrome refers to the injury of one or more of these muscles. This is often caused by extensive participation in athletic activities like throwing a ball, serving a tennis ball or driving a golf ball. Besides chronic wear and tear, a fall or collision can also be a causal factor. Symptoms may include pain in the front, side, back or deep inside the shoulder, especially with overhead movements. A person may experience pain while doing everyday activities, such as getting dressed or completing household chores.
