Clinical Information
  • An idiopathic vascular disorder characterized by bilateral raynaud phenomenon, the abrupt onset of digital paleness or cyanosis in response to cold exposure or stress.
  • An idiopathic vascular disorder characterized by ischemic attacks in the fingers, toes, ears, or nose, associated with pain and pallor. The attacks occur during exposure to cold temperatures or stress.
  • Blood vessel disease that causes exaggerated responses to cold and stress with poor blood circulation
  • Intermittent attacks of ischemia in the fingers, toes, ears, or nose, accompanied by pain, pallor, and prickling; phenomenon applies to secondary symptoms, disease when cause is unknown.
  • Raynaud's disease is a rare disorder of the blood vessels, usually in the fingers and toes. People with this disorder have attacks that cause the blood vessels to narrow. When this happens, blood can't get to the surface of the skin and the affected areas turn white and blue. When the blood flow returns, the skin turns red and throbs or tingles. In severe cases, loss of blood flow can cause sores or tissue death. Cold weather and stress can trigger attacks. Often the cause of raynaud's is not known. People in colder climates are more likely to develop raynaud's than people in warmer areas. Treatment for raynaud's may include drugs to keep the blood vessels open. There are also simple things you can do yourself, such as
    • soaking hands in warm water at the first sign of an attack
    • keeping your hands and feet warm in cold weather
