Rotator Cuff Injury
A rotator cuff injury is a painful strain or tear in the tendons and muscles surrounding your shoulder joint. The rotator cuff is made up of the four muscles and attached tendons which connect your upper arm bone to your shoulder blade. Injury to the rotator cuff may happen through poor posture, falls, lifting strain, and even repetitive stress.
Rotator cuff injury is common among athletes and those whose jobs involve heavy lifting or pull on the shoulders. Although steroid injection or surgery may be needed in some cases, most rotator cuff injuries can be successfully treated with exercise, with treatment taking from 3 weeks to several months.
