A shoulder injury refers to any damage or harm caused to the structures within the shoulder joint, including the muscles, tendons, ligaments and bones. These injuries can occur due to various reasons such as falls, accidents, overuse, or sudden movements that strain the shoulder area. Some common types of shoulder injuries include sprains, strains, dislocations, rotator cuff tears, and labral tears. The severity of a shoulder injury can vary from mild to severe, affecting an individual's ability to perform daily activities or engage in sports. Treatment for shoulder injuries may involve rest, medication, physical therapy, or surgery depending on the extent of damage.
