Do you notice any symptoms such as a numb, prickly feeling in your hands? Are your hands prone to feeling cold? Raynaud's disease is a condition that causes some areas of your body such as your fingers 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, spasms of the small arteries of the fingers and sometimes the toes cause the arteries narrow, limiting blood circulation to affected areas. Occasionally, the blood vessels rupture.
