What is Raynaud disease?

Raynaud disease is a disorder that affects blood circulation, usually in the hands and feet. The arteries (blood vessels) that carry blood to your fingers, toes, ears, or nose tighten. This is often triggered by cold or emotional stress. The decrease in blood flow causes a lack of oxygen and changes in skin color. Over time, ulcers or gangrene (tissue death) may develop if frequent or severe attacks are not prevented.
