I hava had crohns for 22 yrs so maybe I can help. There is a great site Teens With Crohns that your son should check out. The link is http://p081.ezboard.com/btwcmessageboard79543 . I also belong to a group online that I think you'd find very helpfull (or your son if he'd like). Its called Chronnieschat & has a great message board just about crohns as well as many chats. The link there is http://p207.ezboard.com/fchronnieschatfrm1 . If you check out the links section of that message board, you'll find many great crohns sites!
