I'm finding this discussion interesting, because my MIL may have a thyroid problem. She has had an ultrasound and an iodine uptake, but the nurse that I spoke to at her GP's office really couldn't tell me much about the test results. She goes to see a specialist right before Christmas. MIL is 89 years old and moved out of a big 3 story house into an independent living facility in July. She's been feeling very tired and we just assumed it was her age, but maybe it is something else. I hope she doesn't need radiation, because, as some of you say, it may freak her out.
