Pain in the Neck?
The cervical spine is made up of seven bones called vertebrae, and these vertebrae are separated by disks filled with a cushioning gel-like substance. Your cervical disks stabilize your neck and also help it to turn. Decades of movement can really take a toll on the neck as two-thirds of people will experience neck pain at some point in their lives. Researchers estimate that 50% of the population at 40 years of age and 70% of those at 65 years have some level of cervical disk degeneration. Cervical disk degenerative processes can cause radiating pain, as well as numbness and weakness in your shoulders, arms, and hands.
