Sometimes you leave the water running and then when you put your hands forgetting that it's really hot. You feel the first shock of pain, take your hands out, and then about half a second later feel a longer pain. I think it's probably one of two things. Either the first pain is from the skin and the second is from the more sensitive nerves of your bones warming up or the first is from your spine's automatic reaction and the second is the actual reaction.
Re: Why do you feel two flashes of pain when you touch hot water?
