DS1, 9, has mild abdominal pain today. He ate breakfast fine but is walking hunched over and said he couldn't sleep with a pillow because it hurt his stomach. I asked him to jump to see if it hurt, and he did so easily and said it didn't hurt. Because he can jump, does that mean it's not appendicitis? Or does that mean it could still be early signs of appendicitis?
Anyway, he says when he is hunched over it is fine, but when he stands up straight, it hurts. Any ideas what is causing it?
