Shoulder impingement syndrome is a common cause of shoulder pain that may affect anyone who performs repeated reaching and lifting over their heads.

Also known as subacromial impingement syndrome, it occurs deep inside the shoulder, when the bones of the shoulder blade and upper arm chafe against the top of the rotator cuff.

The term Shoulder Impingement Syndrome refers to a situation in which the tendons and bursa (fluid-filled sac) in the shoulder are repeatedly pinched between the upper arm bone (humerus) and your shoulder blade (scapula).
