Need an evaluation: You need to be seen by a physician for this problem. It may not be serious, but it could be due to an autoimmune disease that can cause potentially serious problems that can be prevented or treated. Autoimmune diseases, such as raynaud's phenomenon or lupus, or other vascular diseases such as buerger's disease or other types of arteritis, can potentially damaging effects on the circulation.
