I've had Hashinitos for 17years. I take 225mg of thyroxine daily. Blood results from April showed normal T4 but high TSH. Dose was increased from 200-225. Last test showed normal T4 but high TSH and dr had ordered antibody screening which is also raised. I have a goitre ( always have but more noticeable these days. Talking about referral back to endocrinologist who I saw 3 years ago as I was thyrotoxic. I had spine surgery last year ( July) too. Please help feeling very concerned .
