Just chiming in to say I can see why it would be upsetting, and I agree that you should discuss that...but I also think that, well, he is a person too and it's important to be respectful of his boundaries about his health. Some people just like to keep health concerns to themselves, especially if he really is concerned about something. Anyway, I hope it's nothing serious and I hope he can give you some reassurance about that. I can just sort of see how if I were in that situation I might react as he is... ((((((((treehouse))))))))
