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.
Answer:
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
