I have a goiter that my doctor says has to be removed. My thyroid levels were tested & came back normal, but I have all the symptoms of hypothyroidism - dry skin, thinning hair, foggy thinking, depression, anxiety, extreme sensitivity to cold, & I m tired all the time. I have also tried 3 different antidepressants & all 3 made me worse than before. Is it possible that they re over-looking something?
