Sorry I'm at work and got interrupted. They are sending you to a rheumotologist to make sure you don't have any other autoimmune conditions. These conditions tend to overlap, meaning you may have more than one. But I still wouldn't get worked up about it. I know several people who just have Reyauds and nothing else. You just have to be careful in the cold, make sure you wear good foot wear and gloves, because your extremities are very sensitve to the cold.
