Hi looking for some advice. I'm on t3 only for the past 11 weeks I have a endo app in two weeks and have been asked to do a thyroid function test before I go to my next app. At my last app I asked about t3 and told her t4 was in way working for me she said that she does not recommend it and wrote to my doctor to say so. I don't really want them to knw yet although there has been a massive improvement. Do I just go ahead have the blood test done ? I just don't want to sit there with her condersending and patronizing manner spilling out her bullshit. Have any off you been in a similar situation ?
