Hmmm. Fresia, you might want to look at material about a condition called "Raynaud's Phenomenon," which can be either a disease or a syndrome. The symptoms sound something like those you've described. Check this out at Wikipedia:

One of my brothers has it which is how I know about it. He's also got something called "scleroderma" and apparently the Raynaud's is caused by this "scleroderma" thing. Here's a link for that:

As people used to say on the net, Hope That Helps! Take care.
