I had thyroiditis after having my child almost 4 years ago. I have goiters on both sides..I did the the iodine radiation to kil the thyroid. My Tsh and T4 levels are most of the time in the normal range. I take 200 mcg of synthroid daily, However my blood work done this week said my tsh level was 12.4 and my T4 was 0.78. Before My thyroid was enlarged r lobe 6.4 by 2.7, l 6.5,x 2.4. Isthmus was 1.3 cm thick. So today i go to have my us redone since it has been 4 years and the tech told me that most people who do iodine radiation usually u cant even visualize the thyroid cause it is so small, however mine was super large and she told me that my isthmus was 2x as thick as it should be... They sent the results to a surgeon to read but wont no the results for awhile.. Any Ideas
