Shoulder instability
Shoulder mobility comes with a price, and that is the possibility of shoulder instability. You have instability if the head of the humerus is at risk of slipping out of the shoulder blade socket. The most common cause is a sudden and violent movement, but it can also be due to overuse injuries and articulation’s fragility. You can also have a partial dislocation of the shoulder, which is also very painful. Some people have loose tendons and ligaments with a higher risk of dislocation. Others could be born with a condition that increases the risk of repeated episodes of dislocation or subluxation.
