Headache is defined as a pain arising from the head or upper neck of the body. The pain originates from the tissues and structures that surround skull or brain because the brain itself has no nerves that give rise to the sensation of pain (pain fibers). Headaches can be classified as three types: 1) primary, 2) secondary, and 3) cranial neuralgias, facial pain, and other headaches.
