Your shoulders are the most movable joints in your body. They can also be unstable because the ball of the upper arm is larger than the shoulder socket that holds it. To remain in a stable or normal position, the shoulder must be anchored by muscles, tendons, and ligaments.
Because your shoulder can be unstable, it can be easily injured.

Elbow injuries can be minor or serious and may include symptoms such as pain, swelling, numbness, tingling, weakness, or decreased range of motion.
