What causes lower abdominal pain?
Patient: Hello, my daughter has had a stomach pain for over three weeks, just below her belly button. It is a  dull ache and sometimes the pain increases after eating or being active. She is not constipated nor dehydrated, She has been seen by her Doctor and the emergency room. All blood and urine test have come back fine. She also has a cat scan that came back fine.  Please help. Thank you. Doctor: HI.3 weeks of pain with normal investigations, increases on food or activity. This indicates me a sub-clinical intestinal infection which may not be caught by any investigation. A 5 days- course of an antibiotic and metronidazole is therapeutic and diagnostic too. I hope Widal has already been done for typhoid.
