My TED was successfully treated two years ago by IV steroids .
I have been very well and not had any symptoms of my graves in the 2 years but a month ago I started to feel awful, exhausted and suffered from insomnia. I went to have a blood test and found I was now slightly under active so my GP put my thyroxine up to 75mg, after two weeks my left eye has started to hurt again although I feel very well again and sleep well and am back to being my old self. Any suggestions please.
