underactive thyroid
"Had taken Armour Thyroid for 20 years but starting 2 years ago I experienced brain fog, aches and pains which was thought to be fibromyalgia, no energy, severe headaches, insomnia and hard to get out of bed and always tired. I have taken many tests, scans and seen many Doctors during that time and couldn't find an answer to my complaints. I felt like I was loosing my mind and in desperation began searching the Internet and came across information about Armour.  I understand Forest Labs bought Armour in 2014 and Actavis bought them in 2015 - lo and behold!!! I saw complaints which were identical to mine and quit taking them on Sec. 22, 2015.  I felt better within 2 days and am angry that I lost 2 years of my life."
