my 6 yr old son has had non stop stomach pains for 30 days now as well as fevers. i have taken him to the ED and they said his test came back normal. they have done CT scans, ultasounds, taken stool samples, checked his appendix, looked for signs of the flu; but nothing has come back abnormal. What other test should i ask to be preformed or what specialist should i go to. would a childrens hospital be more idea so their specialist can look at him? im at a lost.
