What is Shoulder Impingement?

Shoulder impingement is when the space between the rotator cuff and the bony acromion around it is narrowed and the bone pinches and irritates the cuff. This happens when the fuff is weak, the bursa is swollen, or the acromion angles down too far. A shoulder impingement can happen when the rotator cuff is weak or when the bursa is swollen. An impingement can cause tendonitis if you participate in any sports or activites that require a repetitive shoulder movement, such as overhead reaching.
