Why when I’m rubbing my hayfevery/itchy eyes does it feel near orgasmic, but as soon as I stop it’s like the very fires of hell are burning my eyeballs?

In: Biology

Your brain uses electro-chemistry to cause the rest of your body to do things.

If your eyes are irritated by pollen the nerves send a signal that they itch. When you rub them your brain experiences reward signals saying, “Good job, you scratched the itch.”

Unfortunately you just irritated or popped thousands of tiny blood vessels by smashing your dirty knuckles into your eyes for five minutes so now they’re even more red and inflamed. This burns.
