My Dr. advised me to increase my t3 on Thursday. She wants me to do this per blood work, symptoms and a low body temperature. I'm going from 50mcg synthroid and 5 mcg liothyronine to same synthroid dose and 10 mcg liothyronine. I upped it yesterday and took the additional 5 mcg she recommended in the early afternoon ( she wants me dosed 2x day). Any way, I got pretty flushed and my right ear went red, I felt more fatigued and my muscles hurt all afternoon. Is this reaction normal? Has anyone else had this type of reaction? Will it go away?
