Eli5: if there are no pain receptors in the brain directly why do headaches/migraines hurt?

353 viewsBiologyOther

Basically title, but from what I’ve gleaned over the years of reading medical books out of curiosity, tv shows—both drama and based in real life ones like Unexplained ER etc—we don’t have pain receptors in the brain for the brain itself, which is how they can do twilight sedation brain surgeries and patients don’t report feeling anyone poking metal tools through their skull jello.

So why in all the realms does it have to hurt so GD much when I get a migraine or headache—not counting tension or sinus headache as those originate elsewhere

The brain isn’t the thing “hurting” in that instance. It’s everything around it, which is very capable of signalling pain.
