Scaly dry skin, always tired, cold hands and feet etc?

I recommend that you go to an endocrinologist and get another entire thyroid panel done, rather than just the one that your regular doctor would do. You could be in just the beginning stage of thyroid disease; you just have all of the clic symptoms here. The entire panel should be evaluated by a specialist, in my opinion, before thyroid disease is totally ruled out for you right now, due to all of your symptoms. A physical exam as well by the same specialist would be important for you. An endocrinologist is the kind of MD who specializes in thyroid diseases.
