I typically feel more of a numbness at first when my hands or feet get cold. The pain sets in when they only warm up slightly. My best advice is hot hands or reusable hand warmers. They have saved me many times during winter. I also used to wear fingerless gloves at school so I had some warmth in my hands. It might be worth talking to your doctor about prazosin. It's a blood pressure medication that can be used to help with raynauds. I'm taking it for a different condition but it's actually ended up helping my Raynaud's greatly!
