I am sorry to hear about your concern but will be happy to assist you. Raynaud disease is a disorder that affects blood circulation, usually in the hands and feet. The arteries (blood vessels) that carry blood to your fingers, toes, ears, or nose tighten. This is often triggered by cold or emotional stress. The decrease in blood flow causes a lack of oxygen and changes in skin color. Let's connect over a call so that we can discuss your concern in details and make a suitable treatment plan for you.
