Raynaud's disease is a vasospastic disorder-spasms in the blood vessels lead to vasoconstriction (narrowing). The disease mostly affects the fingers, toes, tip of the nose and the ears.
Dr. Fredrick Wigley responds: Raynaudâs phenomenon can be a sign of an underlying secondary disease process, and when it starts after age 40 then a good evaluation is needed. Raynaudâs is caused by low blood flow to the fingers and tissues, and in the severe secondary forms it can cause tissue damage. In the primary form it is benign but bothersome.
