I had RAI May 3, 2012. I never had a sore throat post RAI.
I felt hyper for four weeks post RAI; somewhat normal for a few days; week 11 finally showed after showing still hyperthyroid two blood tests prior (weeks 3 and 7) that my Free T3 and Free T4 were in normal range with a very low TSH yet my endocrinologist is not concerned with that. Funny, because around week 11, I started feeling some hypothyroid symptoms and my doctor told me I could start showing hypothyroid symptoms prior to the numbers changing going that way. I'm going into week 14 post RAI now and I am gaining weight with having already carefully watching my diet and exercising diligently every day. I went through a hypothyroid stage when I was drug induced hypothyroid on antithroid drug, Methimazole back in 2011, so I do know the warning signs this time around. I am anxiously hoping that my numbers show this time around that I am now going into a range where I can get on Synthroid yet will not know until two weeks from now when I see my endocrinologist again. Unfortunately, my main issue with all of this has been weight gain despite my diet and exercise efforts, yet I am also in my early 50s and have not gone through the change of life yet, although testing shows that things are changing in that respect. The weight issue though is not that big of an issue for everyone because I am finding we are all so very different in this journey.
So, except for the one issue I mention above, since about week 5 post RAI I haven't even felt hyperthyroid, thank goodness.
I do know two endocrinologists, my current and another I consulted with that by six months for the amount of I-131 (15 millicuries) I had that I should be on Synthroid by then; I do know too in talking to people I know here and online that everyone is different and some get on Synthroid sooner than later post RAI; my endocrinologist said he has two patients who are eurothyroid post RAI now and never changed yet that is not the normal.
I wish you best of luck on your journey…..beach
