When you get a headache from say, constant loud noise, what exactly is hurting if your brain has no pain receptors?

The brain itself has no pain receptors but just about everything else in the skull does. Commonly it's down to irritation of the meninges - the membrane surrounding the brain - or to a blood vessel. Migraines seem to have more to do with nerves in the skull.
