Overview
Raynaud's disease is a disorder in which the blood vessels to the fingers and toes (digits) become abnormally closed off (constricted). The fingers and toes of individuals with Raynaud's disease change color from white to blue to red, often causing them to feel numb. Raynaud's disease is sometimes seen with autoimmune diseases, such as rheumatoid arthritis, scleroderma, and lupus, where the body's immune system turns against itself, causing various symptoms. Other causes of Raynaud's disease include repeated trauma/vibration, abnormalities in the structure of blood vessels, and drug injection into one type of blood vessel (arteries).
