Hi All! I am in Hashitoxicosis hell! I have been taking .88 mcg levothyroxine for 2 years. I was diagnosed with Hashis ( hypothyroid for 10 years ago. I have been on Levothyroxine the whole time with slight increase/decreases over the years with no real issues. In April I was experiencing weight loss, anxiety, panic, sore muscles, palpatations and difficulty breathing. My TSH came back at .49 which is way to high for me! Doc reduced me to .75, still to high, then to .50 which was good but got to tired, I was then doing rotation of .75 mcg/50mcg however got exhausted! I am now on .75mcg and doing better though still some days of high anxiety! I will be retesting in a week for TSH/T3/T4 ( doc only tested TSH in April) Does anyone have any suggestions? Will I ever get back to normal? I am 63 years old and the last time this happened was back in 2010!
