Getting frustrated with not being able to get things regulated. In 2014 my TSH went up to 15.42! Doctor and I were both surprised, as I had been rather stable for several years and felt fine. She had it ran a second time and it came out the same. That's when the Synthroid dosage was changed to 112mcg. TSH in November 2016 was at 0.11. Dosage not changed. My TSH in December, 2017, went up to 3.19. Doctor didn't want to change the dosage because the T4, 1.51, is at the upper end of the range. I've never been tested for T3. I'm feeling very sluggish, have heart palpitations, dry and cloudy eyes, and just feel unwell overall. Am wondering if it should be time for a small dosage increase?
