Itching is complicated; it's closely related to pain. Itching signals come from sensors in our skin that are quite similar to the sensors--the nerves--that tell us something hurts, or whether something is hot or cold. Itch signals are apparently carried by about 5 percent of the nerves running from our skin to our spinal cord. http://encarta.msn.com/encnet/features/columns/?article=BNItching
