Hi I've been on thyroxine 100mcgs for about 3 months dr increased limit to 125mcgs before xmas & I had palpitations & terrible anxiety. Rang gp she said reduce to 100mcgs which I did but still feel anxious. Had thyroid function test 2 to 3 weeks ago not heard result yet! I've been reading a lot of your posts & it seems to me that you have to pay privately to get extensive tests done! Any advice on where to get tests & also advice on anxiety & blepharitis? Also feel cold a lot of the time! What should I do?? I'm a nurse but not practising now so I do have quite a bit of knowledge I'm confused as to what to do?? Can someone help?? Also felt a lump in my neck had a neck scan & they said it was fine!!
