What causes headaches?

ANSWER

The pain you feel during a headache comes from a mix of signals between your brain, blood vessels, and nearby nerves. Specific nerves of the blood vessels and head muscles switch on and send pain signals to your brain. But it's not clear why these signals turn on in the first place.
