My 7 year old son has a protruding lump on his stomach, an inch away from his belly button, to the right, just appeared the other day. Has been complaining of stomach pain for weeks, pediatrician diagnosed him with constipation, he s been taking restoralax with results. I ve also taken him off all gluten (as i have celiac disease ) but he is still having stomach pain. The lump reminds me of a hernia, I had an umbilical hernia myself and it resembles that a bit. Any help would be appreciated. I m a registered nurse.
