Well, sorry if I accidentally belittled you or something you feel strongly about. I didn't mean to. If I may though: your brain itself has no nociceptors (pain receptors). None. At all. Not a single one, that's why they can do open brain surgery on people and poke at them :PHeadaches are actually the meninges, which is a squishy sponge-like barrier between your brain and skull. It softens the impact if you hit your head or whip it around fast so your brain doesn't splat on the inside of your head :)
