Sunshne24, if you saw an Endo, chances are he was only testing for Addison's Disease unless he's a REALLY enlightened Endo. I'm skeptical. Did I already mention that adrenal fatigue is harder to get diagnosed than hypoT?
If you had an ACTH, you'd know. Here's a
description, but ignore the "normal" values b/c they are for full blown Addison's, not Adrenal Fatigue. Sadly, most people with Addison's only get diagnosed when they go into Adrenal Crisis -- how the hell can anyone expect to be diagnosed with Adrenal Fatigue?
Anyway, they take your blood, then they inject ACTH into you and you wait around and get blood drawn 1/2 hr and 1 hr later. The most difficult part is getting the interpretation. Again, most only check for Addisons.
I'm assuming that you only had serum cortisol tested, which really isn't a great test. Most Endos take a cortisol blood test and only test ACTH if the blood test is off. Definately get your test results including TSH, FT3 and FT4, if you haven't already. Something is wrong.
If your tests all come back normal and you have symptoms of adrenal fatigue (do you?), then I would get someone to treat you based on symptoms, which means trying to find an appropriate doctor. As I said, there are difficulties with each and every test when testing adrenal function.
Probably not a journey you want to take right now, but it bears looking into.
