what is raynaud's phenomenon?

1 doctor answer
Dr. Robert Cuff

Vasoapastic response: Raynaud's phenomenon is an exaggerated vasoapastic response to cold weather and stress. The blood vessels of the extremity normally dilate and constrict with temperature changes. This occurs to an extreme degree in patients with raynauds. They will experience blue or white fingers or toes when exposed to cold temperature or stress. This is self-limiting and rarely causes significant problems.
