Hi, I had gone through your question and understand your concerns.
You are a established case of primary
hyperthyroidism and you underwent two times
Radioactive iodine for the same and presently on antithyroid medication... Radioactive iodine is 1st and best treatment modality presently but some times in few cases single dose does not help and we have to go for 2nd dose of radioactive iodine.. but in your case 2nd dose is also failed and you are on medication.. Actually, anti thyroid drug is indicated for 18 months to 24 months beyond this period anti thyroid drug is indicated as per guidelines.. But in few countries , Some doctors are using anti thyroid drug for longer periods...
in your case, i'll prefer surgery now.. because you already had two session of Radioactive iodine ablation but did not help you..
SO for you, Now best choice is surgery.. but its totally your doctor choice... still there is hope for both radioactive iodine and anti thyroid treatment..
Don't be scared for anything.. Start
Beta blocker for your irregular heartbeat.. And Kindly Consult your
endocrinologist for further management ....
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
