?cold urticaria?: There is a poorly understood condition called cold urticaria where someone breaks out in whelps when the skin surface is cold. You can produce the same effect by applying an ice cube to clear skin for a few seconds. The whelp would appear soon thereafter. It is usually benign & transient but your doc needs to rule out any problems.
