hyperthyroidism
"I have Grave's disease with a small node in my thyroid.  Five Dr.'s that I went to, as the previous reviewer stated wanted to radiate and kill my thyroid which would require meds for hypothyroid for the rest of my life.  I then found an endocrinologist who suggested that the node was small and that a small dosage of this medicine may control it.  I was monitored very closely and went into remission after 2 years.  After being okay for another 5 years my thyroid went hyper again and I was put back on a dosage of 2.5 mg/1x per day.  The node has not changed in dimension or mass.  So I am not healed but effectively am under control.  I also have a very minor symptom of Graves' ophthalmopathy, which this medicine controls as well."
