What is shoulder impingement?
Shoulder impingement happens when the tendons of the rotator cuff and the bursa (a small fluid-filled cushion) become irritated in the narrow space beneath the bony tip of the shoulder (the acromion). Raising your arm reduces that space, so overhead movement can pinch and aggravate the sore tissue. You may also hear it called subacromial pain syndrome or rotator cuff related shoulder pain. These terms describe a very similar problem.
