Eventually this can cause irritation and pain in the shoulder. In some cases, a genetic problem with the connective tissues of the body can lead to ligaments that are too elastic. When ligaments stretch too easily, they may not be able to hold the joints in place. All the joints of the body may be too loose. Some joints, such as the shoulder, may be easily dislocated.
Chronic instability causes several symptoms.
Frequent subluxation is one. This commonly happens when the hand is raised above the head while throwing. Subluxation of the shoulder usually causes a quick feeling of pain, like something is slipping or pinching in the shoulder. Over time, you may stop using the shoulder in ways that cause subluxation. The shoulder may become so loose that it starts to dislocate frequently.
