So I managed to get my first and last appointment with an endo. Due to my symptoms, blood tests, (super low tsh, very bad cholesterol, ((and I eat VERY well)), what she could physically feel as a swollen thyroid, my age and gender, (40 yo male), she said she's 90% sure it's Graves disease and RAI will likely be the treatment.
But of course before all that I need an uptake scan and more blood tests to be sure.
