ELI5: Why do surface wounds like paper cuts hurt or sting so much, especially compared relatively to other wounds?
gpt
The above answers (more nerves on your hands/near the surface) are true but another reason that papercuts specifically hurt so much is because the edges of paper are really ragged microscopically (think Velcro), so when you get a papercut it does more damage to your skin cells than if you nicked yourself with a sharp knife.
