Sorry for the typo Free T3 and T4
Thyroid medication takes time to work, that is why they only do blood work every six weeks, If you can post your lab results members can comment and explain them to you.
I don't know if your stomach problems are related to the medication or not. 10mg is not a high dose. See if you can get the lab results Free T3 and T$ and TSH plus reference ranges. Good Luck FTB4
