Questions and Answers about Raynaud's Phenomenon: NIAMS (Excerpt)
Once the attack begins, a person may experience three
phases of skin color changes (white, blue, and red) in the fingers or
toes. The order of the changes of color is not the same for all people,
and not everyone has all three colors. Pallor (whiteness) may occur in
response to spasm of the arterioles and the resulting collapse of the
digital arteries. Cyanosis (blueness) may appear because the fingers or
toes are not getting enough oxygen-rich blood. The fingers or toes may
also feel cold and numb. Finally, as the arterioles dilate (relax) and
blood returns to the digits, rubor (redness) may occur. As the attack
ends, throbbing and tingling may occur in the fingers and toes. An
attack can last from less than a minute to several hours. (Source: excerpt from Questions and Answers about Raynaud's Phenomenon: NIAMS)
Questions and Answers about Raynaud's Phenomenon: NIAMS (Excerpt)
When a person is exposed to cold, the body's normal
response is to slow the loss of heat and preserve its core temperature.
To maintain this temperature, the blood vessels that control blood flow
to the skin surface move blood from arteries near the surface to veins
deeper in the body. For people who have Raynaud's phenomenon, this
normal body response is intensified by the sudden spasmodic contractions
of the small blood vessels (arterioles) that supply blood to the fingers
and toes. The arteries of the fingers and toes may also collapse. As a
result, the blood supply to the extremities is greatly decreased,
causing a reaction that includes skin discoloration and other
changes.

Raynauds Phenomenon: NWHIC (Excerpt)
Attacks are often triggered by exposures to cold or by emotional
stress. During an attack, there is a severe reduction of blood flow to the
extremities which may cause small blood vessels and arteries to collapse.
There may be significant changes in skin color and sensation. An attack
may last from less than a minute to several hours. (Source: excerpt from Raynauds Phenomenon: NWHIC)
