Doctor: Hello! Good Day! I've read your concers and will try to breakdown the anwers for you. Whole body cramping can be from several factors-  electrolyte imbalance, dehydration, lack of oxygen in the body.  However, in your case, it might be caused of lack of thyroid hormones since you stopped your thyroxine.  If I was your treating physician, I will request for the following: thyroid function tests, electrolyte panel (Na, K, iCa), CBC.  Treatment depends on your results.
