TSH on its own does not tell you much, KL. But lots of doctors think it is all they need to look at. You should get your TSH, T4, T3 and T2 measured to see a much bigger picture; you might also want to get your iodine level checked (there is a big relationship between thyroid and iodine).
Several years ago I had some symptoms that I told my doctor about. He ordered a number of blood test, including TSH. The result was that my TSH was high; so he put me on Synthroid. It worked for seven or eight years; then I got a bunch more symptoms, but my doctor said my TSH was fine.
Then I found website Synthroidhaters, which has a list of symptoms that are common with Synthroid use. Most of my symptoms were on that list – I had well over 50% of them.
Just under a year ago, I went to a Naturopathic Doctor (ND) with my symptoms highlighted on the list and he prescribed armour thyroid. After four months all the Synthroid symptoms are gone.
I have been off and on Paleo for most of the year. It seems to help my thyroid functioning. I have seen that some people can go off their hypothyroid meds after being on Paleo a several months (some ND say so, too). I would like to be able to do so. But for lots of reasons, I have not been able to be Paleo for extended times; but I will keep on trying.
