I have to wonder though, why you felt the T4 med was lacking. Generic Levothyroxine is the worst, which could be a source of your problems. It's also possible you have been held "within range" and hypo for years on end.
Unless you keep your TSH in a very tight range all the time, you will suffer. The average TSH is between 0.8 and 1.8, and that's where it needs to be. 3.5 is not fine and will make you ill. Not all doctors realize this. They should, but they don't.
With Armour, you will sure need more than a TSH test. You will need Free T4 and Free T3 tests, because the correct med dose may not produce a very normal looking TSH.
There is a thread in the health pages that lists a website that lists doctors in your area. It is not a complete list, but it may help you.
The button for the health pages is toward the top of the page on the right.
Best of luck to you, and welcome to the forum.
