Cervical spondylitis is a degenerative condition of the cervical spine caused by age-related wear and tear that leads to stiffness and neck pain. It involves the deterioration of intervertebral discs and vertebrae in the neck. Symptoms include chronic or intermittent neck pain and stiffness that may radiate to the shoulders, arms, and hands. Diagnosis involves physical examination and imaging tests like x-rays and MRI. Treatment includes medications, physiotherapy, exercise, ergonomic changes, and sometimes surgery.
