It does sound like Raynaud's but I am just a patient and it's your Dr that can give you a diagnosis. It is a very simple cold tolerance test performed in office. In the meantime, keeping warm and keeping your hands and feet warm are the best ways to avoid the pain of re-warming, such as don't have your hands in cold water. Use waterproof gloves with a liner. Don't touch cold things, use hand warmers, and such.
