Raynauds is spasm : Raynaud's phenomenon is caused by a spasm in the vessels usually caused by exposure to cold. It starts with the finger tips, toes, tip of the nose, and or ears turning white. This is followed by a blue color (cyanosis ). When the blood vessel relaxes the skin flushes as the blood rushes back in. 2 color changes are required for diagnosing raynauds. Cyanosis is is simply blue from lack oxygen.
