Shoulder syndromes refer to a group of conditions that affect the shoulder joint and surrounding structures, leading to pain and limited mobility. Common types include rotator cuff injuries, shoulder impingement, and frozen shoulder. These conditions can result from overuse, injury, or age-related wear and tear. Symptoms often include pain, stiffness, and difficulty in performing daily activities like reaching overhead. Diagnosis typically involves a physical examination and imaging tests such as X-rays or MRI. Treatment options may include physical therapy, medications, or in some cases, surgery to restore function and alleviate discomfort.
