Shoulder pain is a common condition that can range from mild discomfort to severe pain, affecting your ability to lift, move, or use your arm comfortably. It may be caused by muscle strain, tendon inflammation, rotator cuff injuries, arthritis, poor posture, or overuse. Sometimes shoulder pain can also result from nerve compression in the neck. Proper evaluation is essential to identify the underlying cause. With timely care and the right treatment, most shoulder pain conditions can be effectively managed and resolved.
