How are itches created on human skin?

I don't get it. I mean.... it's like ur jus sitting on th floor doing nothing n then all of a sudden, ur leg itches like crazy. Why... or how does that happen? I'm curious.
skin cell are exposed to allergic agent (poison ivy etc) cells release histamine and this starts the chain of allergic reaction including itch, that is why you give ANTI-histamines for itching
im pretty sure it has something to do with nerves
