Neck disorders refer to a range of conditions that affect the structures in the neck, including muscles, ligaments, nerves, and vertebrae. Common causes include poor posture, injury, and degenerative diseases like arthritis. Symptoms may include pain, stiffness, and limited range of motion, which can impact daily activities. Diagnosis typically involves a physical examination and may include imaging tests such as X-rays or MRIs. Treatment options vary and can include physical therapy, medications, and in some cases, surgery. Maintaining good posture and ergonomic practices can help prevent neck disorders and promote overall neck health.
