Intussusception presents as abdominal pain, which occurs in sudden, severe, and periodic episodes. The child cries restlessly with a pale face, and the pain lasts several minutes or longer. The pain then subsides, and during this relief, the child falls asleep. The pain reoccurs every ten to twenty minutes. Continuous episodes occur until the intussusception is successfully reduced, after which the child calms down and falls asleep without further crying or vomiting.
