cervical spondylosis is natural age-related wear and tear of cartilage, disks, and bones in the neck. Like the rest of the body, the disks in the neck area also degenerate with the age. Cervical spondylosis is very common, more than 70% of people over the age of 50 are affected. The condition can lead to stiffness and pain in the neck, although patients generally experience no noticeable symptoms.
