For children with navel pain, whether there is redness, swelling, skin breakdown or discharge from the navel, if so consider umbilicitis and if there is polyp-like tissue or a lump also consider lesions such as umbilical velvet. In addition to the umbilicus and the abdominal wall around the umbilicus, intra-abdominal organ pathologies such as appendicitis, Crohn’s disease, irritable bowel syndrome and ascariasis may also cause symptoms of belly button pain and need to be seen for a definitive diagnosis.
