Hi, 7.94 to some doctors is not considered elevated for your age. I’m also 69 and considered clinical hypo because I have a controlled pituitary tumor. I do take a very low dose of Tirosint. I find when my numbers hit 8 to 10 my already digestive disorder makes my constipation worse but my hypo tuff to regulate and they don’t know why. I see an endocrinologist too.

I would suggest an endocrinologist let her or him do a full thyroid work up. That way you can figure it out. Your tsh can be high but all other tests be normal and most endocrinologist will start with low dose meds.
You need to figure out what’s causing it and more labs can help narrow it down. I’ve also tested positive for ANA but they did lots of tests years ago and one came back slightly elevated so no confirmation. I’ve never been tested since.
Right now I have a rash on the nape of my neck and terrible burning mouth and tongue and it’s daily. All I get is it’s left over from Covid. Sometimes you feel at this age they lose interest, Medicare pays them so terribly so they just do nothing. It’s disappointing but keep pushing for more tests.
Best of luck.
