Raynaud's Phenomenon | Johns Hopkins Medicine
Raynaud’s phenomenon is a disorder that causes decreased blood flow to the fingers. In some cases, it also causes less blood flow to the ears, toes, nipples, knees, or nose. Spasms of blood vessels happen in response to cold, stress, or emotional upset. Secondary causes of Raynaud’s include lupus, scleroderma, and other diseases.
