I have now had two episodes of feelings of swelling around my thyroid and flagged it up with my doctor, under the suspicion that it is thyroiditus from my Hashimotos. I am worried that my healthy thyroid tissue is slowly being destroyed. A previous ultrasound revealed that the left is still healthy. I am currently on 100 mcg's of Levothyroxine. My levels are TSH 1.7, free T4 is 17 and my antibodies are around 300 (they used to be around 900). I said to my doc that if I still have such a high level of antibodies then there is still inflammation within my thyroid. My doctor said they are unwilling to consider changing my dose because my TSH is normal. Does anyone have any experience of this or any advice?
