Signs and Symptoms
  • Raynaud's disease affects the fingers and toes (digits). The digits feel cool and their color changes from white to blue to red.
  • Severe Raynaud's disease can result in skin ulcers. This complication is more common in people who have both scleroderma and Raynaud's disease.
  • People with Raynaud's disease may have more noticeable small blood vessels (capillaries) into their fingers and toes where the nail plate meets the skin of the finger (proximal nail fold), particularly in people who also have an autoimmune disease.
