Just for fun. Has anyone else experienced the elusive itch on your back? You know that itch where you try to scratch it but it keeps moving around your back? Or that itch where you beg someone to scratch your back "a little to the left, a little to the right, up, no wait down, down, no not that far down, quick go up again!" If so, how long does your back usually have to be scratched before you feel better?
