10 Causes of Shoulder Pain
Reviewed: Dr. Mera
Cause #5: Impingement
Shoulder impingement is a problem that occurs when the acromion applies too much pressure on the rest of the shoulder. The acromion, that is, the upper part of the shoulder blade, rests on top of the soft tissue in the shoulder when the arm is raised or extended out from the body.
If someone uses their shoulders too much or too aggressively, the acromion can rub against the tendons in the shoulder. This excessive rubbing is known as impingement and can be a catalyst for problems like bursitis.
