question: My 5yo son has been having very loose stools every time he poops. He was in to see his pediatrician last Thursday & again this Monday. Xray revealed foreign object 2mm in size in his stomach last Thursday. On Monday, they did a follw up xray & saw that it passed. Bloodwork done & came back normal, one level indicating he s getting over a virus. Doctor has him off dairy, he s drinking lactaid for about a week to see if that helps w/ his belly aches. But he still has a white Puss, & yellow, loose stool every time he goes. If his bloodwork & xray are normal, this rules out anything cancer related? What should I keep watch for & report to doctor? Should I get sample?
