Hi, I have changed from eltroxin to armour thyroid meds as I have been taking thyroxin t4 alone for 7yrs and kept deteriorating even though bloods looked balanced, I believe I have autoimmune thyroiditis and wasn't converting t4 into t3 so switched to armour but since I've upped dose my face is burning cheeks and real red, is this a sign I am over treated or is it just initial, is it allergic reaction? I've heard taking progesterone can reduce it? Please help, thanks
