I am on Levothyroxine, but I have heard others say that Armour was the better one to be on. The thyroid issue is more complex than I realized before, and this is all brand new, as of a week ago, to me. Too soon to tell if it will help, but I know for sure that I MUST take some sort of medication because there are some nasties waiting in the wings, including nerve damage, if I do not. Something, probably the Lyrica, is helping with the TN. Or it could be the thyroid meds and the Lyrica. I started them all about the same time. They will take me off the Lyrica down the road, like in a couple of months, to see if the TN is gone. THEN we will know it was thyroid. Hope you can find something that works for you!
