title: Raynaud phenomenon.
abstract: Raynaud phenomenon, a vascular disorder triggered by cold or emotional stress, results from an exaggerated vasoconstriction and vasospasm of the digital arteries and arterioles. The fingers, and, less often, the toes, are affected; ear lobes, lips, nose, and nipples may also be involved. This article describes the difference between primary and secondary Raynaud phenomenon and reviews etiology, diagnosis, prevention, and management of symptoms.
