I’ve searched this up and thought about it and all I can think of is a blood vessel in the brain. But that still doesn’t explain why when people have concussions or get head injuries, they feel pain. So what is a headache or where is this pain coming from if there aren’t any pain receptors in the brain. Nervous system? Are there actual pain receptors?

Most headaches are a mixture of different trigeminovascular dysfunctions. The brain indeed does not have any pain receptors, that’s why a stroke is absolutely painless.
