I’m puzzled by why a doctor would expect a patient to experience a thyroid storm shortly after RAI, but I’m also hoping the experts will clarify this. My brother-in-law is a cardiologist and has been great with providing me lots of information about my Grave’s Disease. His explanation to me of what a thyroid storm was was really scary–he described it as a very serious situation requiring immediately medical attention and hospitalization. He said it was not really all that common, but being a specialist, he saw it occasionally.
