@collegeprof your post started by saying you experienced hyperthyroidism. Then you ended by saying thyroidism was confirmed But you didn’t say hyper (high) or hypo (low). I’m guessing hypothyroidism since you were put on levothyroxin. Is that correct? I had Graves’ disease (hyperthyroidism - high). My endocrinologist told me it is not uncommon to reverse from hyper (high) to hypo (low). She is now monitoring me for this. Is this anything like what has been going on with you?
