I have just discovered that my thyroid is playing up again... My TSH is less than 0.01, my T3 is 7.4, and my T4 is 22. I have been on carbimazole before when I first became hyperthyroid, and I hated it. Lots of side effects, and then a big crash when I got hypothyroid. My ME is now so much more severe, that I am really frightened at the thought of taking carbimazole again. However, radioactive iodine doesn't thrill me either.... Has anyone tried anything else, or do you have any suggestions? Thanks in advance!
