The shoulder is an innately unstable joint
Shoulder injuries can result from chronic overuse, lifting too much, or from high-impact force. Repetitive sports like gold, tennis, baseball, and even swimming can damage this overly flexible joint.
Common Problems with Shoulder Joints
Arthritis: Shoulder arthritis can occur as the cartilage inside the ball and socket of the shoulder joint breaks down. Cartilage protects the surface of the bones located in your shoulder joint. Many factors can cause your cartilage to erode and cause your shoulder bones to rub painfully.
Bursitis: This condition is caused by the inflammation of the shoulder joint that comes into contact with tendons.
Rotator cuff tears: The rotator cuff is a complex structure that connects the humerus to the shoulder blade, and it also makes it possible for the shoulder joint to move and remain stable. When the rotator cuff is compromised, shoulder pain, stiffness, and a loss of motion become the result.
Labral Tears: The labrum is responsible for reinforcing the ball-and-socket joint of the shoulder. It allows for the shoulder bones to move freely and painlessly. When you tear your shoulder labrum due to physical trauma or prolonged wear and tear, you may suffer from pain and a limited range of motion.
