My daughter has been very healthy all her life. I have never had to give her an injection. She has never had to got to the emergency room for any illness.She has been on cortef and florinef all her life. She is a little overweight but sits in front of the computer a lot. I was surprised to see how many problems some of the other children on this message board have. I don't know if it is luck, genetic; (mom and dad were always healthy) or a good endo. but I am satisfied with Dr.Root. Good Luck!
