Nothing has really been ruled out, Mostly in my opinion, I just can't seem to get anyone to realize how ill I am. I have been diagnosed with hypothyroidism and sicca syndrome, but beyond my Liothyronine prescription, my primary and my rheumatologist don't seem to be looking for anything else and haven't prescribed anything besides cyclobenzaprine for fibromylagia and temazepam for my intractable insomnia. .
