This is a really dumb question. I've always been told that the brain has no pain receptors, allowing people to undergo open-head surgery with only anesthetic acting on their skin/bone tissues.

Why do we feel pain when we have headaches? How about chronic headaches? You can even feel which part of the brain is it coming from...

The tissues of the head, surrounding the brain are sensitive to pain, so abnormal stimulation of these can cause the sensation of pain.
You then feel that the pain is coming from a particular focus in your head.

So the pain comes from the external surface, not the inside... Thanks!
