If you are an athlete in a throwing sport—most notably, if you’re a baseball pitcher—rotator cuff tendinopathy is an issue that’s probably on your radar. But you should also be aware of this chronic shoulder injury if you’re nearing 40 or beyond.

Rotator cuff tendinopathy (sometimes called tendinopathy of the shoulder) is, generally speaking, an overuse injury affecting the tendons of the shoulder. If you have this shoulder injury, your primary symptom is usually pain. You may also experience related issues affecting your shoulder joint, like tenderness and limitations to your normal range of motion.
