It is never normal to have abdominal pain, to start with. And even less to have it regularly. Bowel movement after meals is relatively normal (of course, depending on frequency, intensity, etc.), as a consequence of something called the gastrocolic reflex. Your symptoms might suggest an enhanced/exaggerated gastrocolic reflex, that is not uncommon as part of, or in relation with, an irritable bowel syndrome.
Every morning shortly after eating breakfast I get extremely severe pain in my lower abdomen which lasts anwhere from 20 seconds - 5 minutes. When the pain stops I feel the urge to pass stool which I do and then get relief. The pain feels like a griping pain as if I ate some bad chinese food or something. I have been to 3 gastroenterologists who have done 3 colonoscopies and endoscopies and found nothing.
