My Son's Jewish Stomach

I have discovered three words that leave me feeling both helpless and suspicious. 

"My stomach hurts."

Again? Does he have a fever? Any other symptoms? Does he just want to get out of going to school? Did he eat something bad? Is it anxiety? Can Honey Bunches of Oats cause food poisoning? When did I buy the milk? Do I need to get the vomit bowl? If I tell him to walk it off and then he projectile vomits, how severely will I punish myself?
