Hi I have Graves disease & have had rai treatment, 4 yrs ago. Since then I ve been on 200 meg of a liquid form of levothroid. My problem other than intense weight gain, I breakout in hives constantly. Usually after something has graised my skin. My face, arms, hands, feet, neck all over. Any idea what this could be? My grandmother had lupus, I didn t know if that could be a symptom.
