Raynaud’s Disease

Raynaud's disease is a condition that causes some areas of your body – such as your fingers, toes, tip of your nose and your ears – to feel numb and cool in response to cold temperatures or stress. It's a disorder of the blood vessels that supply blood to your skin. During a Raynaud's attack, these arteries narrow, limiting blood circulation to affected areas. Typically, fingers or toes change color on cold exposure appearing white or blue. Women are more likely than men are to have the disorder. It's more common in people who live in colder climates.
