I was not sure where to post this but I guess hormones are relevant! BACKGROUND My son was diagnosed with CFS by KDM aged 4. He has had Lyme disease and bartonella since birth and has plenty of symptoms of both - which of course overlap with CFS. He is now 9. He has adrenal fatigue, morning cortisol very low. THE PROBLEM He has genitals which are small for his age and don't seem to be growing at all. I am worried that this could be caused by the infections he has, or hormone imbalance. I don't know what to ask my doctor to test, or how to go about tackling this. Any advice at all would be much appreciated.
