I should also say that in March of last year, I had a large heating lamp (like the kind they keep outside) fall on my head and had a concussion. A CT was done and they didn't see anything, but I felt out of it for at least a month afterwards.
I've never really felt 100%, even when I was younger. But, it has really been this last year that I've started to feel worse. My emotions are all over the place, making it hard to be around people. And my mental state is a lot lower, it's just so much harder to think.
I've read that antibodies are almost always negative. I have mildly elevated TPO and Tg antibodies.
The most common cause of hypothyroidism in industrialized countries is Hashimoto's thyroiditis. You have the antibodies for that.
Central hypothyroidism - both secondary and tertiary - is much rarer.
You should assume Hashi's is your bane. Besides, treatment for hypoT is the same, no matter the cause.
