What is Raynaud’s?
Raynaud’s (ray-NODES) is a disorder of the small blood vessels of the extremities, reducing blood flow. When exposed to cold, the blood vessels go into spasms, which may cause pain, numbness, throbbing and tingling. Emotional distress may also trigger such a response. The fingers are usually the primary affected areas, although toes, nose, ears and other extremities may be involved. In a typical case, fingers turn from white or blue (or both) within minutes of cold exposure then become red when they warm up. These color changes, which may vary from person to person, are an exaggeration of a normal response to cold exposure. A normal cold response in the hands is a blotchy red and white pattern. Raynaud’s-type color changes are distinctively different.
Approximately 5-10 percent of all Americans suffer from Raynaud’s, but only one out of ten sufferers seek treatment. Both men and women suffer from Raynaud’s, but women are nine times more likely to be affected. Some researchers estimate as many as 20% of all women in their childbearing years have Raynaud’s.
