Do acupuncture or moxibustion have effects on blood circulation and cold hands and feet?

My legs swell easily, and even a slight chill causes my hands and feet to become cold, turning my toenails purple. Even when I exercise, I feel like my blood circulation isn't working properly... I heard that a friend with similar symptoms started visiting a Korean medicine clinic, but I haven't heard how effective it was since it was early on. Has anyone received treatment or experienced benefits for similar reasons?
