May I know your age and gender please.
When you say 'neg hashimotos' are you implying that TPO and/ or TG antibodies
were checked in the blood and they were negative?
It is tricky to analyze TSH and free T4 in the concurrent situation of thyroiditis
and micro adenoma
in the pituitary. Further tests will help us understand this better:
T3 resin uptake
8 am cortisol
Midnight salivary cortisol
If you are male: then FSH , LH and Total Testosterone
If you are female and your cycles are not regular, then : FSH LH and Estradiol
is not recommended for the treatment of hypothyroidism
