my Mom was nuts most of my life and misdiagnosed as bi polar
turns out it was thyroid cancer ,,after they removed it she was a different woman
So I do know they have drugs that can keep chemicals right in your body ,,
You need to talk all that over with your doctor
that little gland does a lot ,and I have seen the effects of it being out of whack ,,
I hope your problem is manageable (I have an auto immune disease eating my spine so I get that too ,and knew 2 people with Lupus ,not something I would wish on my worst enemy )
Wish you well ,,please make your doctor go over your options
many people can give you advice ,but its like my back
lots of people have bad back ,but not all of our problems are the same
