Cold Fingers/Hands

Does anyone have problems with cold fingers and/or cold hands? During the winter my fingers are especially suseptable and become very numb. I have heard of some condition (forgot the name) so I looked it up on webmd.com and the pictures they showed were exactly how my fingers look when they reach that certain state. When they get cold and numb I rinse them under warm water and they turn white (white as a piece of paper, it's rather gross) then gradually they turn purple, then back to normal. So when I came across the article below it sounded somewhat related, although it doesn't travel up my arms. Just wondering if anyone else suffers from this. Quote from article on www.wcsn.com www.wcsn.com/.../news.jsp "My main goal is to spend as little time in the water as possible,'' she said of competition days. An angular woman with a model-thin body, Coughlin gets cold easily. "My hands get numb and it is all downhill,'' she said. "I can't turn it around. It starts in my fingers and progresses up my arms. Once that happens, I'm useless in the water.''
