I'm in the US, but still looking for advice. ALL normal thyroid bloodwork, no antibioties present. Every test has been run. Ultrasound shows slight to moderate enlargement of thyroid. Diffuse nodules too small to FNA. I've had 2 docs tell me I have all he symptoms.....only 21 & 1/2 my hair has thinned and is yuck. I'm desperate for answers. Only slightly deficiency in a few vitamins. Exhausted, moody, brain fog...college student & feel terrible!
