What is a rotator cuff injury?
The rotator cuff is a group of four muscles and their tendons that wrap around the top of your arm bone and keep it centred in the shoulder socket as you move. An injury can mean an irritated or overloaded tendon (tendinopathy), a strain, or a partial or full tear. Some come on suddenly, such as a fall or heavy lift, while many build gradually from repeated overhead use or age-related wear.
