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.

Symptoms include changes in skin color (white to blue to red) and skin temperature (the affected area feels cooler). Usually there is no pain, but it is common for the affected area to feel numb or prickly, as if it has fallen asleep. (Source: excerpt from NHLBI, Raynaud's Phenomenon: NHLBI)

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)
