Raynaud's disease. Print. Raynaud's (ray-NOHZ) disease causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress.

What Is. Raynaud's is a rare disorder that affects the arteries. Arteries are blood vessels that carry blood from your heart to different parts of your body. Raynaud's sometimes is called a disease, syndrome, or phenomenon. The disorder is marked by brief episodes of vasospasm (VA-so-spazm), which is a narrowing of the blood vessels.
Raynaud's disease is a rare disorder of the blood vessels, usually in the fingers and toes. It causes the blood vessels to narrow when you are cold or feeling stressed. When this happens, blood can't get to the surface of the skin and the affected areas turn white and blue. When the blood flow returns, the skin turns red and throbs or tingles.
Raynaud’s phenomenon is a disease that affects your blood vessels. There are two forms of Raynaud’s phenomenon: Primary and secondary. The form of Raynaud’s phenomenon you have affects the symptoms you have. Symptoms of Raynaud’s phenomenon can vary from mild to severe. Most people have mild symptoms.
Raynaud’s (ray-NODES) is named for the French physician Maurice Raynaud, who first recognized the condition in 1862. The disease causes an interruption of blood flow to the fingers, toes, nose, and/or ears when a spasm occurs in the blood vessels of these areas.
