Raynaud’s Phenomenon (Raynaud’s) is a condition where very small blood vessels go into spasm or “clamp down” in response to cold temperatures. When this happens, this reduces blood flow to the extremities, usually the fingers and toes, causing them to turn white and feel cold. On re-warming, the skin usually turns another colour such as blue or red before returning to normal.
