My son had an X-ray of his stomach do to some pain on the lower right side. The xray showed a lot of fecal matter and his ped told him to take magnisium citrate. We did it and he had a BM but still had pain. We put him on a liquid diet the next day and tried magnisium citrate again. The pain has lessened but he still has some pain. No fever, nausea , vomiting or pain standing sitting or walking upright. We would like to try a heat pad?
