Re: Besides hyperthyroidism, is there something else going on?
I'm certainly no expert on nodules or hyperT. But it does appear they're evaluating whether you have a hot nodule causing yours. See the part in the report that says, "Cannot exclude a hot nodule"? That would be a good thing, actually, better than if you had Graves' disease. It would be easier to treat. A hot nodule has an almost zero chance of being cancer, not to worry much about that.
Sorry I can't help much more than that. Let us know what happens at the endo's.
