Why do some minor injuries hurt more than the severe ones?

That may be something to ask a medical doctor, but I’ll take a stab (lol) and say perhaps it’s because the big ones are somewhat blocked by your brains pain sensors?

I don’t know, but this is so true. I have a sprained knee and bruised hip from a car accident (that almost flipped my car on the highway), and those hurt way less than this tiny crack I have on my thumb from dry skin. Which hurts like a muthafluther!!

Might have to do with how many nerves are in a given area or how much a given area moves. For example, banging your head may not hurt as much as damaging your elbow because your elbow, by design, moves more than the bones of your skull.
