Opinions on Cytomel vs Armour?

Hello - I have been posting on and off post lobectomy a year and a half ago. My TSH numbers are in the “normal” range. I have not felt right since the surgery. I have gained 20 pounds terrible muscle pain. My hair is falling out, I am exhausted. Currently I am taking75 mcg levothyoxine. I met with a new endocrinologist and explained how awful I felt. He suggested taking Armour or adding Cytomel. Has anyone had experience with either of these meds? Thank you!
