I have Raynaud's, and its mostly in my toes. I don't always get the typical red white blue color changes. Most of the time my hands and feet are cold, and my feet turn blue very often. They are also purple at times, and swell. I had terrible ulcers this winter, and went on Prednisone and Procardia, which seemed to help. If you are concerned with your feet and hands, you should see a rheumatologist - they are the ones who deal with it. Good luck!!!
