Why am I always cold? Blood tests less than a month ago were all normal-no vitamin deficiencies or hypothyroidism.

Inadequate tests . Most people who feel cold all the time are hypothyroid. Many who are hypothyroid have "normal" T4 and TSH levels. Unless you had your free t3 (liothyronine), (liothyronine) reverse t3 (liothyronine) ; thyroid antibodies checked thyroid problems have not been ruled out. A holistic md is likely to do adequate tests. See http://bit.Ly/1bogdxh ; http://bit.Ly/1cjnybx.
