Dear Dr, About eight years ago I had a thyroidectomy. Lately, however, I feel cold even on a warm day or when wearing warm clothes. Moreover, although I feel cold in fact I perspire. Is there anything I can do to regulate my skin temperature so as to reduce this problem. Thank you. My age is 67, height 1.53m, weight 65 kg. The thyroidectomy was performed to remove non-malignant cysts.
