Hello sir, I was diagnosed with hypothyroidism 1 year back.(tsh 9.83)My symptoms were shortness of breath and third half of eyebrows gone. I was told to take 25mg thyroxine tablet and after few months tsh went back to 5. Recently when I took the test it was 9.4 again. So increased the dosage to 50 mg. But now it feels like my neck is swollen and shortness of breath isn't getting any better. What do I do?
