After a year of methimazole for Graves,
my TSH raised to normal levels and
my free T4 normalized. After a few months of no treatment,
my TSH level began to rise in January 2014, and hasn't stopped. At first my endocrinologist was reluctant to prescribe more than a token amount of levosynthroid, although I was becoming symptomatic with hypothyroid symptoms. She feared Graves disease returning.
