ken, re the nodule on the thyroid. While its important to define if that nodule us a problem, know that the reflex action is to remove that thyriod. You have two, so the thinking is taking one is ok.

Having had one of mine removed, I can say there is a reason for two. And replacing thyroid hormones adequately and correctly is a problem. IF a doctor can be convinced to follow you, IF you can get a doc to understand the problems..... getting the right hormone support takes monthes, even years to get right.

While removal might be necessary, doing everything to keep both thyroids would be my recommendation.

In my case, A nodual can be benign. I wish now a biopsy
had been suggested, or I had been more vocal about keeping my thyriod. Docs do what is fast and easiest. No looking ahead at the damage and side effects.
