Shoulder Impingement Symptoms and Causes
Shoulder impingement results from pressure on the rotator cuff from part of the shoulder blade (scapula) as the arm is lifted. It is one of the most common causes of pain in the adult shoulder. Those who perform a lot of overhead activities are susceptible to shoulder impingement. Symptoms can include pain while lifting and reaching, and stiffness and pain that radiates from the front of the shoulder to the side of the arm.
