I've been suffering from practically all the symptoms of hypothyroidism for over 8 years now. It has been a living nightmare. I came across the symptoms of an under active thyroid a couple of weeks ago and the hairs on my arms literally stood on end, I have so many of the symptoms. I went to my GP and she agreed to do a thyroid test, I was sure it would show there was something wrong but she told me today that my test results were normal. My TSH was 0.67 and my FT4 was 12.8. Does that mean that my T4 is at the low normal range? My GP insists it's not my thyroid but has agreed to do a T3 test and test for antibodies. This is all very new to me....any help is greatly appreciated. I've tried everything to feel well....even agreed to antidepressants and mood stabilisers in the past, even though I knew it was not depression causing my symptoms. Now I'm told I probably have fibromyalgia or ME.
