Lynn,doctors told me my blood was normal for months after ptu
but i was going through hell with losing weight, the heart and more
i had to make my own choice and took rai even knowing my blood was normal
even when one doctor told me wait another 6 months i ran for the rai treatment
i hope im making sence you see even with levels normal you can still be living
in hell its called the war disease, and its name is graves.
