Complex hypothyroid issue, so much suffering

Hello,
I am a 40f obese facing chronic pain surrounding my eyes, eyeball from last 5 years mostly flaring during winter months. MRI showed eye muscle inflammation and high grade partial empty sella. I have hypothyroidism from last 25 yrs btw. I had endometrial hyperplasia last year as well, biopsy was normal.
This year i was low on medication while vacationing, missed few doses of Levoxyl. Suddenly I have noticed that the eye pain intensity got down by 50%. After returning home talked to my Endo and he lowered the dose (100 mcg to 50mcg) but still whenever i was taking medication eye pain headache comes back. So he changed the brand to Tirosint thinking that may be fillers are causing reactions. Tirosint also didn't suite me. Finally he changed to Armor thyroid at its lowest dose 15 mcg. But even if on 15 mcg I am getting heart palpitations, eye pressure etc. My recent lab work showed
t4=1.1;
t3=2.6 ;
TSH=20.
TPO antibody =25
Currently i am in a situation where TSH going high but still i can't take any medication as eye pain intensifies. Is there any possibility that csf pressure causing this intolerance due to empty sella? I am so confused and scared about thinking that there is something going very wrong with my body!!
Appreciate your advice.
