Answer 2

Answer:

Headache is pain in the head or face, and sometimes also includes pain in the upper neck. Pain sensitive structures in the head and face include the skin, bone and structures in the eyes, ears, nose and mouth.Headache pain results from signals interacting among the brain, blood vessels and surrounding nerves. During a headache, an unknown mechanism activates specific nerves that affect muscles and blood vessels. These nerves send pain signals to the brain.
