my 8 yr old has recently been complaining of severe stomach cramps after eating. it doesn't matter what he eats whether it be plain toast with butter or a spicy plate of spaghetti. within minutes after eating he is crying in pain. his ped put him on Zantac for a 2 week trial and it has done no good. we go back to the dr today for a follow up. any help or suggestions is greatly appreciated!!!
