eli5: Why do you feel pain when you have a stroke or haemorrhage even tho the brain has no pain receptors?

928 views

I remember hearing somewhere that your brain has no pain receptors, as if something touches or damages it, you’re already dead, there’s no need for it to feel pain. Could it be it feels pressure rather than a genuine pain? Or is this total bollocks?

I don’t have the answer but I can tell you that they kept my dad awake during brain surgery and they had the same reasoning: the brain doesn’t feel pain. It was a trip. I’m sure they must’ve used something because I know they used a saw to open the skull to get to the brain.
