I have been taking thyroxine for 24 years since my first child was born. My thyroid levels were always fine until I had a hysterectomy and started to take HRT. Since then my levels always read as too high although I feel well. I do not have a high blood pressure, show no symptoms of being hyper but doctors insist I reduce my dose. I have tried this in the past but feel rotten when I reduce. Has anybody else had an experience like this?
