HIGH TSH AND HIGH T4

Hello All,

7 months ago September 2025, I noticed my throat was enlarged and that's when I got an ultrasound on my thyroid. The findings where the texture was heterogenous, left lobe was increased 5.1 x 1.5 x 2.7cm and right lobe was 5.3 x 1.7 x 3.3cm. no nodules were noted.

I got a thyroid panel done at the same time sept 2025, I found that my T4 was 2.17 ng/dl and my TSH was 15.227 ulu/ml, T3 is normal, my thyroid peroxidase AB is 600 iu/ml and thyroglobulin is 4,000 Ui/ml. Since sept 2025- Mar 5 2026 my TSH and T4 are both consistantly high.

So I was referred to an endocrinologist and I mentioned if this had to do with my pituitary gland so at first he was saying no because my prolactin levels were good but a couple days later he called and put in an order for me to get one. The results were that pretty much everything was normal except my pituitary gland was midly prominent in size. thats all.

I am and have been experiencing all the symptoms of hypo and hyper, waking up feeling hungover, heart racing and heart fluttering, headaches, foggy vision, brain fog, bone pain, along with back pain, heat and cold intolerance extreme fatigue and dry eyes. My next appointment is later this month.

Id like to know your thoughts and what I shouldnt except for treatment and what ideas you have that should be ruled out. I have felt like death for 2 years now and only 7 months ago im getting an idea on why.

I am 24yr FM.
