What causes lower abdominal pain and nausea in children?
Patient: Yes. My son is 10. He has been sick for 7 months. He complains of pain in his lower abdomen (colon area). He has nausea but not really throwing up. They have him on amitriptyline(anit depressant) to help dnumb the muscles & nerves. But all his blood work & tests came back good. But they did not run a colonoscopy. Is it possible for him to have colon problems and it not show up in blood work. My mom has crohns since she was small. Her Gi dr says colon trouble can be silent & my sons drs could be missing it. Without a colonoscopy they cant rule it out. Is this possible? Doctor: Dear Parent,Your child's long lasting lower abdomen (10 months) pain is a cause of concern. Given a family history of Chrohs disease it is pertinent that Crohn's disease is ruled out in your child. The most definitive test for Crohn's disease is to take a small sample of tissue from his colon( biopsy) during colonoscopy  and study it under a microscope. It is surely possible that your child can have Crohn's disease with  a normal blood work up. I suggest that you consult a gastroenterologist as soon as possible who can help diagnose your child's condition and initiate appropriate treatment.
