Hello, @dosina. I'm 73...74 in a few days and have spent the past year dealing with the same/similar symptoms, getting progressively worse. This experience ended in Nov. 2020, Mayo.

I, too, was fearful I was re-experienceing dreaded menopause. I was not.

I began taking levothyroxine several years ago. I was just below normal for my age group. A couple years ago, dosage was increased gradually. Then, the new symptoms started.

Night sweats got to the point my head would get very hot and hotter, beginning at night then off and on all day. Then,, add sweating to the point I had sweating running down my face, neck, all over my head, then my whole body was involved. I had chills, my anxiety level kept going up, couldn't stop talking, agitated.....etc. I told several doctors who didn't connect to thyroid.

When admitted through ED after episodes thought to be BP related, 'fainting ' on getting up from a stretcher or chair, Mayo docs zeroed in on the thyroid. My hypothyroid was hyperthyroid due to over medication.

My dosage was cut back to 122mcg from 157mcg. Within days I began improving. Calmed down, fewer tremors, no 'hot heads', no sweating, no fainting and generally much improved!

I am still feeling better. Everything seems to be working better. I hope this story helps you w/yours. It may not be the same, but now you have more information to add to the pot.

Wishing you well and blessings on this journey.
