I have been ill for awhile now. I have a full feeling in my throat with noticable swelling under my chin with pain.. I have a rosey rash on the front of my neck and a burning pricking sensation on my skin,mostly on my upper body, back, arms, face and scalp, made worse by going in the sun or getting warm. I have had weight gain. I am having vision problems (blurred vision) that are intermittant. The Dr did do blood work (a CBC) that looks normal. I asked him for a T3 comparison test and he said that the TSH (T4) is all that is needed. What do you think?
