I feel like so much has happened since my last post and yet not. Let's see.... I had another test a month and a half or so later (maybe two) to see if my tsh, free t4 and free t3 levels had changed and they had not. Although I will say overall I've been feeling much better. That is until my doctor said, "Let's do a RAIU" which is a Radioactive Iodine Uptake test. The reason this test is used is to see exactly what is going on. He knows I have a nodule on my thyroid and wonders about Toxic Goiter. Up to this point I had been doing all he asked and to be honest, it was all simple blood tests and such. Oh and the saliva test which put me down for awhile but still...I wasn't taking toxins into my body. I was struggling with this RAIU because you take a little pill that is actually radioactive iodine. The next day, they do a scan and that will show them what's going on. The cons: I have enough health issues, I don't need to add toxi...
