My hands are always cold and often go numb. My nails will also turn a light purple color where the nail meets the skin. Is this something I should be concerned about?

There are several nutritional deficiencies that might cause that. Doctors have no training in nutrition, so you have to learn it yourself. Books by Adelle Davis are the most popular introduction to the field even though they are rather old.
