It could be a ton of stuff, lots of it easily solved. They might fix it before even needing to do a scope. I say take him in- it will not be fun, but neither is being in pain w/o knowing why. Scopes are unpleasant, but represent a finite, known quantity when it comes to suffering. Whatever he's got is unknown, and could be infinite, if left untreated. You need to have more information, and the only way to get that is to go to a doctor.
Edit: Also, as others mentioned, include your son in the conversations. He's old enough now to start to understand about
his medical care. He might not be ready to handle it on his own, but he should certainly have a voice in his care at this point. I was diagnosed at 16, and my parents talked to me, gave advice, and ultimately let me make the final decisions (though we have a habit of forming consensus about
such things). That was, I think, VERY important for me developmentally. It gave me... a sense of comfort and control. I knew exactly what was happening, why, and how it was supposed to affect me. All the while, my parents were there, being supportive but not controlling. I still like to drag them along for the more serious procedures, like my surgery last year.
