Important Info on Signs of Raynaud's and Attacks

Symptoms of Raynaud's: Changes in Skin Color and Sensation

For someone with symptoms of Raynaud's, there can be 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.

How Long Do Symptoms of Raynaud's Phenomenon Last?

During an attack, symptoms of Raynaud's phenomenon can last from less than a minute to several hours.
The period of exposure to the cold is extremely critical, because it only takes about 20 to 30 minutes of exposure to the cold to cause potentially serious problems, such as tissue damage. This can lead to ulcers on the fingertips and, if left untreated, even gangrene. Bone damage may also occur.

Frequency of Raynaud's Attacks

The frequency of Raynaud's attacks varies from patient to patient. Some people may get them as often as daily or several times a week.
Since Raynaud's phenomenon appears to be more common in people who live in colder climates, are the residents of Florida or the typically warmer climates completely safe? Not necessarily. People with Raynaud's who live in milder climates may have attacks during periods of colder weather. It doesn't always take very cold temperatures or long periods of exposure to bring on an attack. Attacks can occur whenever temperatures dip below 60 degrees. For some people, sticking their hand in the frozen foods section at a grocery store for just a few seconds can be enough to trigger symptoms of Raynaud's.
