I’m afraid I don’t understand your doctor’s thinking. When my dose of Synthroid kept getting raised, the doctor was trying to get my TSH lower and lower….every increase resulted in lower TSH. When my TSH was very low I had a lot of symptoms so my new Endocrinologist was trying to get my numbers into the range where the side effects were reduced. If your TSH is at the higher end, the increase should cause the TSH to go down and MIGHT help with your side effects. Definitely ask for a referral for an Endocrinologist who specializes in Thyroid Cancer! if she does not give you one, you might want to ask the surgeon for it….no one should suffer without exploring changes in medications/dosages to see if the symptoms improve. Good luck!
