Causes of shoulder joint injury

1. Age factor: Middle-aged and elderly people are prone to shoulder joint diseases. With the increase of age, the tissues of the shoulder, including rotator cuff and ligament, undergo degenerative changes, and the elasticity of the tissues gradually loses, becoming stiff and more vulnerable to injury.

2. Repeated overuse of upper limbs: it is a common pathogenic factor of shoulder joint diseases. In particular, people who are engaged in occupations that require repeated upward movements and athletes who need overhead movements, such as baseball, volleyball, tennis, swimming, etc.

3. Trauma: it is the primary pathogenic factor of shoulder joint disease in young people;

It is worth noting that other diseases (such as chest diseases, gallbladder diseases, liver diseases, heart diseases or cervical diseases) can also cause shoulder pain.
