I have a multi-nodular goiter on the left side, I'm 30 yrs old female. when I was 15 i had hyperthyroidism with large goiter and nodule. This was treat with radioactive iodine in low dose. Goiter shrank and I was not on any hormone therapy, left side was found to be destroyed/inactive. Now nodules are growing slow in the left side, biopsy was clear, ultrasound shows original nodule is calcified. Others are fluid filled or solid. My hormone levels are on the high end of "normal" Right side of thyroid is slightly enlarged. I want the left side removed as it is causing compression issues, pain in my neck, jaw, and headaches. I can't sleep well for pressure on my neck. My Endo. says surgery is not necessary. I am worried because i do not understand the growth of the nodules after the radio-iodine therapy and why endo. thinks this is a non-issue.
