question: hi, I have a problem with my hands that i think may be due to circulation. They are always cold, and always red if it is warm outside/purple if cold from fingertip to wrist. My hands sweat at an abnormal amount which may have to do with my condition. They turn normal color when i put them above my heart but as soon as I drop them back down they turn back to red/purple. I m wondering if you know what I have and how I could fix it. Thanks.
