Well actually, the ultrasound is just the tip of the iceberg. I have a ton of medical problems and right now the thyroid is being ignored, Not by me, by my ENDOCRINOLOGIST. So, I was just trying to get some input about the ultrasound b/c I'm going to a thyroid specialist, not endocrinologist, in July and I want to have as much info as I can get. I will NOT walk out of that office w/o answers!
