My doctor upped my dose from 60mg to 90 mg for hypothyroid ... I had been on armour for 4 years and been doing great. All of sudden I felt all the symptoms of hypothyroidism... Being on the 90 mg showed that the TSH AND T3/T4 are normal but I still have weakness and weight gain that seem crazy. I workout 4 to 5 times a week but now I can barely make it through one class ... What can I do ? I know that lab has changed the fillers of the Armour, could this effect my reaction to the Armour ?
