Your son sounds like mine. My son is 20 now, but missed most of his senior year of highschool. He has had this since age 13. Currently, he is living at home because he got so ill with EBV that he had to quit his job training program. In July, his EBV settled in his abdominal lymph nodes and caused painful inflammation that hasn't gone away. He was hospitalized due to that. We are currently working with an immunologist and a natural healing doctor. Nothing seems to be working. He catches other viruses as well. He can't stay well and doesn't remember feeling truly healthy. We have tried everything, I think, but are desperate for help. This is disabling for him.
