Increase in armour yet T3 & T4 does not go up


New here - good morning everyone. Here's my story

Started on armour at 1/4 grain & slowly increased but hypo symptoms remain. I am currently on 2 grains for the past 2 months. In the last 18 months the highest my free T3 has ever been is 3.0 and the highest my free T4 ever got to 0.9. I will say my energy & brain fog have improved slightly but I am nowhere close to feeling good. I still have low temp 96/97, my hair is rubbish - dry, brittle & shedding. My hands are so rough & dry that my nail beds hurt & are jagged. To add another layer of complication I am 56 and in menopause. I am using HRT patches to help with meno symptoms. It is a normal dose 0.50 patch however I am aware that HRT can affect your thyroid meds (I cannot give up my HRT though). My iron & ferritin have been low but I have been taking supplements & my new results show a slight increase.

I got my lab work done privately & my SHBG & testosterone is very high & I read SHBG can bind thyroid meds too. My question is - should I be increasing or lowering my armour medication? What can I do about the high SHBG? Please let me know your suggestions. Below are my recent labs:-

Don't worry too much about blood tests when on Armour or any other NDT, as the tests were introduced for levothyroxine (T4 only) therefore if we add T3 to T4 or take NDT tests do not correspond. It is all about how the patient feels on a dose and relief of clinical symptoms.

When taking NDT you can raise it by 1/4 tablet every 2 weeks and I will give you some chapters from a doctor who was an Adviser to before his untimely death. He only took a blood test for the initial diagnosis and thereafter it was titrating doses slowly until symptoms were relieved.
