What is Raynaud's Phenomenon (also called Raynaud's Disease or Raynaud's Syndrome)?

ANSWER

Raynaud's phenomenon causes spasms of the small arteries of the fingers and sometimes the toes, brought on by cold or stress. Certain occupational exposures bring on Raynaud's. The episodes produce a temporary lack of blood supply to the area, causing the skin to appear white or bluish and feel cold or numb. In some cases, the symptoms of Raynaud's may be related to underlying diseases such as lupus, rheumatoid arthritis, and scleroderma.
