As far as I can tell, this site doesn't get a whole lot of traffic. Little traffic for those with Addison's any how. I'm sorry to hear your son was diagnosed and only 9 years old. I was diagnosed at age 13 with Addison's and I know how frustrating and scary it can be as a child when diagnosed with something no one really knows a whole lot about.
Anyhow, I'm now a parent and can understand both the parent's side of dealing with a child diagnosed and the child's point of view. If you ever want to chat or ask questions, let me know. I've delt with Addison's for 22 yrs now and have had complications crop up through out the years. Good luck to you and your family. I hope doctor's are able to find a medication your son's body will absorb. Take Care, Leah Fedeli
