Shoulder pain is a common musculoskeletal complaint in primary care practice. Approximately, 20% of the general adult population experience at least one episode of shoulder pain in their lifetime. To understand the condition, it is important to understand the shoulder anatomy. The causes of shoulder pain primarily include, impingement syndrome-rotator cuff disease (impingement syndrome), glenohumeral joint disease (adhesive capsulitis or frozen shoulder), acromioclavicular joint disease, and referred pain. Shoulder pain can be easily diagnosed through analysis of medical history, physical examination, and radiological findings in clinical settings.
