Most people have headaches from time to time. But if you have a headache more days than not, you might have chronic daily headaches.

Interactions between impulses sent by the brain, blood vessels, and nearby nerves cause headache discomfort. Unknown mechanisms cause certain nerves that control muscles and blood arteries to become active during headaches. The brain receives pain signals from these nerves.
