Raynaud's (ray-NOHZ) disease is a condition that causes some areas of your body — such as your fingers, toes, the tip of your nose and your ears — to feel numb and cool in response to cold temperatures or stress. In Raynaud's disease, smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas.
Women are more likely to have Raynaud's disease. It's also more common in people who live in colder climates.
Treatment of Raynaud's disease depends on its severity and whether you have any other health conditions. For most people, Raynaud's disease is more a nuisance than a disability.
