All You Need to Know About Shoulder Muscle Pain
The shoulder is the most flexible joint in your body consisting of three bones namely humerus (upper arm), scapula (shoulder blade), and clavicle (collarbone). The top of the humerus is ball-shaped, and it fits into a shallow socket present in the scapula. The ligaments in the shoulder help to keep the ball centered in the socket while the rotator cuff muscles allow you to rotate and lift the arm.
