Raynauds Phenomenon?: Raynaud's phenomenon occurs when the extremities of the body, usually the fingers and toes, change colour and may become painful. It is due to a narrowing (constriction) of the small blood vessels on exposure to the cold, or to a change in temperature, or to emotional stress. In most cases, the cause is not known.
