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?
In: Biology
The pain doesn’t come from the brain, it comes from pain receptors elsewhere. In fact, this is the case for most organs in your body. When you have a stomach ache, you don’t really feel it *inside* your stomach, just in that general area. Most of the time you couldn’t pinpoint exactly where either, unlike if you poked yourself in the tummy with a toothpick. What happens is the organ borrows the pain receptors of specific nearby areas, and sort of projects it there. Headaches are the same.
