You haven’t said what your successful treatment was, so it is difficult to say whether or not you need to nag your doctor some more. We aren’t medically trained here, so your best bet, if you are worried, IS, most likely, to nag the doctor. A fever is not Graves’ related, however. And not wanting salt isn’t art of it either as far as I know.
I hope you are feeling better soon.
