Raynaud's disease or Raynaud's syndrome as it is sometimes called is a common disorder that causes your fingers and toes to become very cold and numb, says Jay D. Coffman, M.D., chief of peripheral vascular medicine at Boston University Medical Center.
Raynaud's is a condition in which the blood supply to the extremities, usually the fingers and toes, but sometimes also the ears and nose, is interrupted. During an attack they first become white and dead looking then red and burning. There may be considerable pain, numbness or tingling.
The best thing one can do it to get some heat to these areas. Having a Quantum Heat Pack available for this that one can heat up instantly can handle the painful symptoms of Raynaud's very quickly.
