Shoulder pain refers to any discomfort or stiffness felt in or around the shoulder joint, which includes muscles, tendons, ligaments, and bones. It can arise from overuse, injury, poor posture, or medical conditions like rotator cuff injuries, frozen shoulder, arthritis, or bursitis. The pain may be sharp, dull, constant, or only occur with specific movements, and can limit daily activities such as lifting, reaching, or sleeping. Shoulder pain may also radiate to the neck or upper arm. Early diagnosis and proper physiotherapy treatment are essential to relieve pain, restore mobility, and prevent long-term complications.
