Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. Typically the disease affects the fingers, and, less commonly, the toes, though it rarely also affects the nose, ears, nipples, or lips.
