Shoulder impingement syndrome is a painful condition in the shoulder. Pain occurs when the tendons in the shoulder are irritated or inflamed from repetitive overhead motions or structural abnormalities in the shoulder. Impingement usually occurs due to muscle imbalance around the shoulder that place can increase the stress on the rotator cuff tendons. Symptoms can include a generalized aching pain in the shoulder and arm. You may feel weakness and pain when you move your arm overhead, for example putting on a jumper or brushing your hair.
