Hello. Wonder if you can help. I did have hyperthydrodism up untill 2009, was not working right so after many years my consultant suggested I had tablet to kill off the remaining thyroid. I was put then onto 75mgrms. of thyroxine, which worked for some months, then had to up it to 100. Here we are some time later and is still reading 22 p/c. Am having bad side effects, like depression, musle pain and gengeral fatigue. Will this go on continuously?
