What is mild impingement in the shoulder?

Mild impingement in the shoulder, often referred to as subacromial impingement syndrome, occurs when the tendons of the rotator cuff or the bursa become compressed or irritated as they pass through the subacromial space. This can lead to pain and limited range of motion, typically during overhead activities. It is often caused by repetitive overhead movements, poor posture, or anatomical variations. Treatment usually includes rest, physical therapy, and anti-inflammatory medications to alleviate symptoms and improve function.
