So perhaps its best to go and see your doctor and ask, at the very least, for a Free T3 and Free T4 (thyroid hormones) test. Your doctor will probably advise that you simply take just the TSH test - which is highly inaccurate on its own. So I would insist on the TSH plus the Free T3 and Free T4 tests for the thyroid gland. Your series of tests, to give a complete picture, should also realistically include blood tests for ferritin(anaemia), adrenal hormones(stress), TSH, T3, T4, Reverse T3 and a test for Vitamin B12 levels in the blood. This is described in more detail in the links below.
For a proper understanding and much more detail on how to actually cure your own thyroid problem and symptoms (using the lugols iodine protocol and natural bio-identical hormones) you should also try to read Dr Brownsteins two books which will give you a much greater understanding of your problem:
Iodine: Why You need it, Why you Can't Live Without it
The above books can also be found on Amazon.
And also from Dr Brownstein, here is a simple link that quickly describes, in fair detail, some surprising reasons as to what really causes hypothyroidism, its particular effects on the body and what you can actually do about it.
