What is the definition or description of: raynaud's phenomenon?

COLD FINGERS/TOES: The small blood vessels in our fingers and toes normally clamp down a bit when we are exposed to cold to keep our body core warm. People with raynauds have an exagerated response to the cold. The blood vessels clamp down too much and relax too slowly. This results in pain + color changes; classically blue, white, then red. Most raynauds: not associated with an autoimmune disease, but sometimes is.

Depends: Raynaud's disease is a primary vasospastic process that usually involves the fingers or toes and is worsened by cold, stress, vibration. Raynaud's phenomena is assoc. With other collagen vascular diseases such as lupus, etc. It is a vasospastic process that compounds the microvascular occlusive disease present in some of these disease states.
