looking for some advice for my num. T4 around 18 and tsh 0.8 previous to These latest blood results. She has been told to increase to 250 mcg but doesn't want to as she was on this dose a couple of years ago and had bad chest pain when a gp told her to stop it immediately and then had to increase from the beginning.
Just wondering, why would there be such a big change in her results? Any advice gratefully appreciated
