I'm a woman in my late sixties. I was diagnosed hypothyroid about 15 years ago and my TSH levels have fluctuated badly ever since. I have known only once before what it is to be hyperthyroid when my TSH levels went too low but for most of the time the extreme opposite, hypothyroid symptoms, was my normal, making me feel really unwell even though my blood test results were within range. However, since being diagnosed with smouldering myeloma 14 months ago my doctors have been more understanding and allowed me a thyroxine prescription that produced a TSH level from 0.25 to 0.15, with a normal T3 level, and I've had almost a year of feeling very much better - well, even! I now need treatment for the myeloma but, disappointingly, my TSH level has suddenly decreased in just a fortnight from 0.15 to 0.07, with my T3 level at the high end of the range, and I'm feeling awful again but now with a lot of the symptoms of hyperthyroid! I ought to add that I have decreased kidney function, having lost a
kidney to cancer eight years ago, as well as various other less serious issues
and quite a few allergies! I feel almost in despair as to how to manage all this while coping with chemotherapy as well. Any help, advice or information that I can take to my GP appointment tomorrow would be very much appreciated. Thanks for reading this.
