I got this from Medline http://www.nlm.nih.gov/medlineplus/
There is more information on Raynaud’s at the website.

What is Raynaud’s Phenomenon?

Raynaud’s Phenomenon is a Disorder of the small blood vessels that feed the skin. During an attack of Raynaud’s, these arteries contract briefly, limiting blood flow. This is called a vasospasm. Deprived of the blood’s oxygen, the skin first turns white then blue. The skin turns red as the arteries relax and blood flows again. Extremities–hands and feet–are most commonly affected, but Raynaud’s can attack other areas such as the nose and ears.

What are the symptoms?

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.

What causes Raynaud’s?

Doctors do not completely understand the cause of Raynaud’s, but they believe the body’s blood vessels overreact to cold.

When the body is exposed to cold, the hands and feet lose heat rapidly. To conserve heat, the body reduces the amount of blood flowing to these areas by narrowing the small arteries that supply them with blood. In persons with Raynaud’s, these small blood vessels overrespond to cold. For example, reaching into a refrigerator may trigger an attack.

Cold temperatures are more likely to provoke an attack when the individual is physically or emotionally stressed. For some persons, exposure to cold is not even necessary; stress alone causes vessels to narrow.

I’ve been looking for a discription of this disease and it’s symptoms and haven’t located it.  I’m sure someone has posed it but with so many e-mails I must have missed it.  Just wondering.

Thanks,  Lynn

    My fingers sometimes get numb and turn a white waxy color. There is no pain and no sensation of cold. This happens randomly. It involves one or two fingers on either hand and lasts from 5 to 20 minutes until the numb sensation ceases and then the blood flow returns to the fingers making them pink again. Is this reynauds syndrome?
