why can something like a cut not hurt until you notice it?

Question

This can also go for things like pimples. Anyone?

Answer 1

If you get seriously hurt, your brain doesn’t want to waste time being in pain. Instead, it wants to put its energy into getting you to safety. If it’s a smaller cut then maybe you were preoccupied with something more important (playing a sport) and you just were so focused on something else that your brain didn’t have enough resources to feel pain. Or sometimes you might have nerve damage.
