ELI5: Why does hitting my hand against something hurt more when it's cold?

It's now winter here, and any time I pump gas or work outside, and I bang my hand against something, it hurts so much more than when it's warm. Wouldn't the cold numb my hands? Why does it seem to hurt so bad? (I don't mean the pain from the cold itself).

Cold dulls your nerves, and makes them less sensitive... EXCEPT FOR PAIN NERVES. They actually function *better* at colder temperatures. You have to be *really* cold for those nerves to become *less* functional, cold enough that you have bigger problems with hypothermia and frostbite.
