Hi, for the past 30 years I have been going on and off to the Doctor's (at different practices - I have moved around a lot) with symptoms and have been tested regularly, probably once a year, for Thyroid function. The Doctors always tell me that the test has come back low but not low enough for them to be able to do anything about it. My symptoms are very much indicate what I understand is "under-active" thyroid please forgive me if that terminology is incorrect. Next year I will be 50 and I am really tired of feeling like this and want and need help. The last test I had they told me the result was within "normal" limits. And the last time I saw my doctor she told me that I was a "perfectly healthy woman". I went to the doctor's last evening and asked for a copy of my last thyroid function test and the reading says that the TSH was 2.8. Now from what I have looked at online since, this seems to be a low reading and I think that I should have been referred for further testing. Please can anyone shed some light on this for me please. Thanks so very much.
