Just signed up! I have an apparently normal 2.7 TSH but following an ultra sound on my thyroid I have been told by my Dr that I have cists on either side of my thyroid, but not on it. A couple of these are calcified. The Dr has prescribed 25gm of thyroxin - T4 levothyroxine sodium, daily (6 weeks ago). Over the last few weeks my throat has become sore and when I sing I am never sure what sort of sound is going to come out (I am a singer so not very convenient!!). I think this maybe something to do with my thyroid. Wondered if others have any comments on this. As an addition I had breast cancer surgery 18 months ago and am taking Adcal D3 and Letrozole. I also have a large gall stone (which I have been told could be a result of a poorly functioning thyroid).
