A. "hem" means blood, it's a very common bruise - when you fall off your bicycles, you get hit. if you don't cut yourself too in the process- blood vessels usually get ripped and blood flows to that area. this causes a red/blue color. after a couple of weeks it'll change color to green and then yellow. this is the blood cells disintegrate.More discussions about haematoma
