Overview of Shoulder Impingemnt
Inflammation or swelling of rotator cuff tendon covering the upper arm bone (humeral head) is called rotator cuff tendinitis. Shoulder impingement means pinching of the rotator cuff tendons between proximal humerus bone and bony acromial process of scapular blade. Impingement occurs when arm is lifted front or sideways. Lead to tendon inflammation, swelling which further leads to less room for tendon to move (Vicious cycle) and leading continuous pain more with movement that involves lifting of arm.
Repeated unaccustomed overhead activities like weekend house hold works or cleaning.
Bony spur under the acromion – some  old patients have tendency to develop spur which causes pressure over cuff tendon.
Overhead athletes e.g. swimmer, cricket bowlers  or sports involved in  repetitive overhead activities may lead to impingement if the stabilizing muscle are weak.
Shoulder impingement is most common cause of shoulder and arm pain in young adult persons.
