I had thyroid cancer and started Synthroid after Levoxyl was back ordered at the manufacturer. I have gained two pounds a month for a total of 24 pounds in a year with no major eating/exercise/life-style changes. I had a systemic histamine response to a bug bite and was put on prednisone for 21 days. After one week, I felt amazing! Pre-cancer energy levels, sleep and metabolism. I stopped gaining weight and lost four pounds!
I felt so good I went in for a blood draw - only to be told I was in the "normal range." Now that I am off prednisone, I am slipping back into thyroid zombie land. Any ideas as to why this may be?
