Why Does My Shoulder Hurt?
Your shoulder is a ball and socket joint and very mobile. It may hurt for many reasons, from injury and overuse to chronic conditions or diseases. You need to know the cause to get effective treatment.

Causes of Collarbone Pain: Everything You Need to Know
Collarbone pain is usually caused by an injury, such as a fracture or joint separation. However, your collarbone (clavicle) can also hurt because of health conditions like arthritis or even certain sleeping positions.
What are dead hangs? What are the shoulder pain risks, and how do I do them safely?
While dead hangs may be OK for people with good upper-body strength and no shoulder problems, they can be risky for others. People with shoulder hypermobility (excessive motion of the shoulder) or shoulder instability (such as those who easily dislocate their shoulder) may need to be cautious. The shoulder, by design, is a relatively unstable joint. It has a large ball-type bone called a humerus, which sits in a relatively small socket called a glenoid.
Scapula Fracture
A scapula fracture is an uncommon injury. The scapula, or shoulder blade, is a wide, flat bone that sits behind the rib cage. The scapula connects to the clavicle (collar bone) in the front of the body, and to the humerus (arm bone) at the side. Part of the scapula is lined with cartilage (the glenoid) and forms the socket of the ball-and-socket shoulder joint.
Repetitive Pitching Decreases the Elbow Valgus Stability Provided by the Flexor-Pronator Mass: The Effects of Repetitive Pitching on Elbow Valgus Stability
Baseball pitching induces a large elbow valgus load, stressing the ulnar collateral ligament. Flexor-pronator mass contraction contributes to valgus stability; however, repetitive baseball pitching may weaken the flexor-pronator mass contractile function. The present study investigated the effects of repetitive baseball pitching on the medial valgus stability measured using ultrasonography.
