My mother has Graves disease, brother has Hoshimotos, one sister hyperthyroid, one sister hypo. I have been diagnosed with chronic hives, went to an allergist, completed poke tests and I'm not allergic. He sent me for labs and everything came back "normal". Besides the hives, I have sensativity to extreme temperatures, fatigue, joint pain, and the inability to lose weight. My labs are as follows. TSH 0.770, Free T4 1.1, anti-thyroglobulin <15.0, Anti-thyroid peroxidase 37.8.
