Signs and Symptoms
- Dull ache in the front or side of the shoulder.
- Painful to lie on the shoulder.
- Discomfort lifting the arm, reaching across body and behind the back.
The tendons in the shoulder slide through a very narrow passageway and attach to the shoulder bone. Impingement occurs when the space between the bones in this passageway is reduced. This can occur from repetitively moving the shoulder into a stressful or suboptimal position. When this occurs, the bones in the shoulder pinch down on the tendons and cause shoulder impingement. Be aware of movements such as climbing with the elbow in a chicken wing position, mantling over the lip of a boulder and jamming cracks with the thumb down.
