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

355 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

pain doesnt have to be real your brain can just start yelling PAIN and then you can feel pain wherever brain says pain in

phantom pain, you lose your right arm and you brain can say you have pain in your right arm
