Overview
Raynaud's phenomenon (RAY-noz), in medicine, is a vasospastic disorder causing discoloration of the fingers, toes, and occasionally other extremities, named for French physician Maurice Raynaud (1834 - 1881). The cause of the phenomenon is unknown, but emotional stress and cold are classically triggers, and the discoloration follows a characteristic pattern in time: white, blue and red. It comprises both Raynaud's disease (primary Raynaud's), where the phenomenon is idiopathic, and Raynaud's syndrome (secondary Raynaud's), where it is secondary to something else.
