I read, a long time ago, that during a physical, doctors normally take a basic thyroid test. But, that test is incomplete for so many issues. So, I asked for the complete series to be done, and my doc did it. Unfortunately, mine was normal. Glad yours showed deviation.
You know what I mean here! :rof
If it's thyroid, it's easy to treat. I'm glad for you. No more bipolar town for you, unless you'd like to visit that is!
Shalom!
