So sorry to hear of your struggles!
It never ceases to amaze me that some doctors prescribe Armour yet don't seem to be aware of the prescribing instructions.
If you look at the treatment section on the Armour website, you will see that Armour is indicated as a pituitary TSH suppressant.
This means that people who are optimally medicated on Armour will have suppressed (below-range) TSH.
Thyroid textbooks indicate that healthy people have TSH 1.0-1.5 so, your most recent TSH level is higher than that, let alone be one that's appropriate for someone taking Armour.
I'm happy to see you're finally getting a FreeT3 test done. I don't know a single person who would feel good with your most recent level (and the same applies for your FreeT4 level).
You need a higher Armour dose.
