ELI5: Why does bumping your shins or stubbing your toe have a worse pain a few seconds after?

Hurts. Send help.

Your nerves are taking a second to tell your brain that you've been hurt.

Each one is composed of different fibers that send messages back to your brain in real time.

A delta fibers are like the messenger on the bicycle that can get there really fast and are usually the response to things like a burn or contact with chemicals.

C fibers are the messenger that has to go on foot and are the ones that respond to pain caused by blunt hits like stubbing your toe so they need an extra second.
