What is Raynaud’s Disease?
Raynaud’s is known as Raynaud’s disease, Raynaud’s phenomenon and Raynaud’s syndrome. It is a medical condition in which the circulation to your fingertips is interrupted. The fingers, and sometimes toes, will turn pale and white as they have no blood supply. After a while they turn blue, and you may experience discomfort or pain.
