What Are Migraine Headaches?

Migraine headaches results from the combination of blood vessel enlargement and chemicals released from the nerve fibers that coil around these blood vessels. During the headache, an artery enlarges that is located on the outside of the skull under the skin of temporal artery. The artery enlargement releases chemicals that cause inflammation, a pain and the further enlargement of the artery.

A migraine headache causes a sympathetic nervous system to responds with feeling of nausea, diarrhea and vomiting. The response also delays the emptying of the stomach into small intestine which decreases blood circulation and increases sensitivity to light and sound.
