Which shoulder muscle is hurting?
A common cause of shoulder pain is soreness of the tendon (a cord that attaches a muscle to a bone) in the rotator cuff. This is the part of the shoulder that helps circular motion. Another common cause is soreness of the subacromial bursa (a sac of fluid under the highest part of the shoulder).
Why does the top of my shoulder hurt when I lift my arm?
Shoulder impingement is a very common cause of shoulder pain, where a tendon (band of tissue) inside your shoulder rubs or catches on nearby tissue and bone as you lift your arm. It affects the rotator cuff tendon, which is the rubbery tissue that connects the muscles around your shoulder joint to the top of your arm.
