You should see an endocrinologist and see if you really do have this issue and if it is still a problem and if anything needs to or can be done about it. Don't go see some alternative medicine clinic or something first. Go get evaluated by a real doctor, take a list of your real symptoms along with your recollection of your early diagnosis and treatment. If you can ask your parents or someone about it, that might also be good.
Best of luck. Let us know what happens.
