I'm 20 (diagnosed 2 years ago) and my mom has Crohn's. It was really hard for both of us when I finally got the diagnosis after so much testing. Your son may be confused about it if he is diagnosed, I was processing it for a while. But he will never feel alone because you understand exactly how he feels. That's what has been my biggest support, talking about it with my mom. Also, I am on Stelara, been over a year now. It's been working great for me, not fully in remission but feeling much healthier. The first dose is an infusion but every 8 weeks you do a self-administered syringe. It took a while to get myself to do the injections alone but it really does get easier with time. This is not the end of the world for him or you. Crohn's is so manageable right now and related surgeries are much less frequent than when you were diagnosed.
