I have a very enlarged thyroid and was wondering what might be causing this. I am trying to get in to see an endocrinologist but they said the soonest they coudl say me was May and June for several of doctors with good reviews in this area. My bloodwork seems relatively normal. here are some of my results: TSH - 1.750 Thyroxine (T4) - 7.1 Sedimenation Rate-Westergren - 2 C-Reactive Protein, Quant - 0.2 Antinuclear Antibodies Direct ( ANA Direct ) - Negative I was diagnosed with Lyme disease 8 years ago and have been in treatment off and on for that over the years. It seems my symptoms never really went away even with hardcore antibiotics and herbal (combined) therapy. I just seemed to be wasting thousands and thousands of dollars with no improvement to show for it. Anyone a thyroid expert? What could be causing this? My doctor mentioned a goiter which could be caused by lack of iodine but that can't be the case as I have done lots of iodine supplementation in the past. I stopped that as I read it could be bad for Hashimoto's (which I assumed could be a possibility) but iodine off or on never seems to affect my lab work one bit.
