Named for the French doctor Maurice Raynaud (1834-1881), who first described it Raynaud’s syndrome or Raynaud’s or Raynaud’s phenomenon is a condition disorder of the small blood vessel that feed the skin.
During an attack of Raynaud’s, these arteries contract briefly limiting blood flow. This is called a vasospasm; the attacks are vasospastic attacks. When 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. The spasms may last a few minutes or several hours. Most often affecting young women age 18-30, in whom it appears 20 times more than often than in men, happened especially during cold weather. It also can happened after exposure to changes in temperature, either hot or cold, as well as emotional situations.
Over time the skin of the fingers becomes smooth and shiny, and the blood vessels become smaller in diameter and lessen blood flow, and small painful ulcers may appear., which left untreated, may progress to gangrene.
Symptoms include changes in skin color and skin temperature where the affected are feels cooler.. Usually there is no pain, but it is common for affected area to feel numb or prickly, as if it has fallen asleep.
Two types of Raynaud’s:
*Primary Raynaud’s or Raynaud’s disease
*Secondary Raynaud’s
Primary
Raynaud’s also known as Raynaud’s disease, idiopathic Raynaud’s phenomenon, or primary Raynaud’s syndrome.
