Neck pain commonly develops from mechanical dysfunction rather than structural damage. Prolonged screen use, poor posture, repetitive movements, or sudden trauma such as whiplash can restrict movement in the cervical spine. When neck joints become misaligned or lose mobility, surrounding muscles tighten to compensate and nearby nerves become irritated. This leads to stiffness, reduced range of motion, headaches, and pain that may radiate into the shoulders or arms. Without correcting these biomechanical issues, neck pain often becomes persistent and progressively limiting.
