Shoulder pain is discomfort or ache in the shoulder joint area, involving muscles, tendons, ligaments, or bones. Common causes include rotator cuff injuries, impingement syndrome, frozen shoulder, bursitis, and arthritis. It can affect people of all ages, with athletes, older adults, and individuals with physically demanding jobs being more susceptible. Shoulder pain can also be linked to radicular pain originating from the neck, caused by nerve-related issues in the cervical spine like cervical radiculopathy due to herniated discs or nerve compression. Patients may also experience symptoms of instability and impingement, making it essential to address the underlying cause for appropriate treatment.
