underactive thyroid
"I have been on Armour since October '13. I was diagnosed hypothyroid. I have steadily gained weight ever since I started. 20lbs. It has not helped with my cold hands or feet, dry skin, or fatigue. My hair has stopped falling out so bad but that is about the only thing good I can say about this. Also, Im not sure if its related  but I've had serious worsening of lower back pain since starting this. "
