You can experience joint instability or pain when the soft tissues surrounding a joint fail to support it, causing instability and dislocation.
What are joint instability and pain?
The joints in your body, like that in the shoulder or upper arm, are firmly held in place by the socket lining, cartilage, ligaments, and tendons surrounding them.
When, because of an injury, whether from a car accident or sports, the surrounding soft tissues weaken, stretch, tear, or cannot support the joint, you can face joint instability and pain in the area.
You can experience dislocation of the joint when the ends of the bones forming the joint get partially or entirely removed from their original position.
While acute joint instability is caused by sudden and severe dislocation of joints, chronic joint instability is characterized by recurrent dislocation of joints.
