I had a thyroid test dune 3 weeks ago and it came back as 5.20, a doctor told me this is way to high, and i have an under active thyroid. I went to another doctor who told me it was fine, i got some thyroid tablets, but have since had them taken off me.So i went on to the internet and have had to buy my own tablets, t4. Can anyone tell me if they have had any problems like i have, and what your thyroid should read
