I've been taking Armour (started at 15 mcg, went to 45, now on 45 per day) and there's no improvement. Have been experiencing severe pain of the neck, mouth and other muscles. Have been told that T3 would help with muscle pain. It is almost unbearable. No one - including my doctors - knows what's happening. I have already tried all other forms of thyroid supplements and Armour was my last effort. Have you heard of these symptoms before? Any thoughts would be much appreciated. Thank you...
