What Is Neck Pain?
By Brian Joseph MillerMedically Reviewed by Sanjai Sinha, MD
A pain in the neck is a common symptom of back pain, arthritis, and muscle strains.
A person with neck pain has discomfort in one of the structures of the neck, and it's a fairly common problem; about two-thirds of the population has neck pain at one time or another.
The neck is a delicate, hard-working area of your body that connects your body with your head and is very prone to strains and damage. It is made up of seven vertebral bones that lead into the cervical spine and support your head, which weighs about 10 pounds. Neck bones are supported by a network of muscles, nerves and tendons. The bones are separated by vertebral disks, and extend into the upper back and spine.
