Raynaud's Phenomenon

Raynaud's Phenomenon Overview

Raynaud's phenomenon is a vessel abnormality caused by overactivity of smooth muscle in the wall of arteries, leading to blood vessel spasms (vasospasms) of the small vessels that supply blood to the arms, legs, hands, and feet. Raynaud's phenomenon is usually diagnosed in people younger than 40 years of age and occurs five times more frequently in women than in men. The disorder is sometimes referred to as "white fingers disease."
