Almost every scleroderma patient has this condition. Raynaud's can involve an abnormal sensitivity to cold in the extremities, a temporary change in color and sensation in the fingers and toes, changes in skin color, pain and occasionally ulcers of the fingertips or toes. If you have Raynaud's, there are some basic lifestyle changes you can make to prevent or decrease the severity of the symptoms, such as dressing warmly and limiting outdoor activities in cold weather.
