Do you feel some sort of a “twinge” in your shoulders? Have you been swimming or doing any sort of rigorous physical activity after a long time? These “twinges” are a sign of a possible rotator cuff injury. It’s caused because of an overworked shoulder.
The rotator cuff is a group of four muscles connecting tendons that attach your upper arm to your shoulder blade. At the top of the shoulder, there are muscles called as supraspenatus and there is subscapalaris present in the front of the shoulder.

Infraspinatus and teres minn are present at the back of the shoulder. All these muscles together form the rotator cuff.
This group of muscles helps lift the shoulder up toward the head and away from the body. As we grow older, we tend to loose the elasticity in our muscles. Tendons also become vulnerable to shoulder injuries.
