it was about 0.5 cm- the doctor did do his own ultrasound
The decision to do FNA on thyroid nodules has to do with size.
If 10mm (1cm) or larger in any direction, than FNA is automatic with most thyroid docs.
they didn't run antibodies
DId he at least run antibodies?
they did an ultrasound and found a small nodule and enlarged thyroid but no goiter- the endo said that it wasn't necessary to do FNA?
Has the doc done an ultrasound with FNA to make sure the thyroid is ok? Are you being treated for the thyroid?
As I have said in other posts, your doctor did not test you at correct times consistently, and without a stim test, treatment should not be started.
Pregnenolone is a precursor hormone - so it can turn into many things - it may not be what you want it to be though so it may create more issues instead of solve them. You cannot test if you are taking OTC glandulars - they will throw off the testing.
