I'm writing to close this out.
Son is home, fever is no problem, he's very weak, but he recognizes it. He's sleeping a lot, and he's allowing himself to sleep. He sounds good on the phone.
He was sick for a long time but didn't pay attention to the pain until his appendix burst. That's his pattern, and I can't imagine where or how he picked it up ... although my W thinks she knows.
He sounded great on the phone, though, so in a few hours we'll probably want to call and berate him for not taking care of himself.
After all, that's the best way to get him to change, right?
Thanks again for your thoughts.
