Pain in the shoulder suggests a shoulder injury which is more common in athletes participating in sports such as swimming, tennis, pitching and weightlifting. The injuries are caused due to the over usage or repetitive motion of the arms.
The term arthritis literally means inflammation of a joint but is generally used to describe any condition in which there is damage to the cartilage. Damage of the cartilage in the shoulder joint causes shoulder arthritis. Inflammation is the body's natural response to injury.
The term SLAP (superior‐labrum anterior‐posterior) lesion or SLAP tear refers to an injury of the superior labrum of the shoulder. The labrum is a ring of fibrous cartilage surrounding the glenoid for stabilization of the shoulder joint.
Playing more overhead sports and repeated use of the shoulder at the workplace may lead to sliding of the upper arm bone, the ball portion, from the glenoid–the socket portion of the shoulder. The dislocation might be a partial dislocation (subluxation) or a complete dislocation causing pain and shoulder joint instability.
Frozen shoulder, also called adhesive capsulitis, is a condition characterized by pain and loss of motion in the shoulder joint. It is more common in older adults aged between 40 and 60 years and is more common in women than men.
