So, I just kinda quit taking my thyroid medicine and I know its supposivily not good to just quit taking it but, I have now began to have hives and the hives are on my arms, legs, and my sides... I went to my doctor and she prescribed me predisone to clear it up along with a shot, for the most part they had all cleared up but they are back and very itchy and sting really bad. My question is, is it possible that they are caused by me not taking the medicine?
