The sufferer, usually a child, may be completely
pain free between attacks. Characteristically, the
pain moves from one spot to the other on the abdomen, in keeping with the movement of the bowel loops in the abdominal cavity.
Asking the child to turn to the left side will demonstrate this shift as the area of pain and tenderness will move along with the bowel to the left.
In appendicitis, the pain may initially start around the umbilicus, then moves over to the right iliac fossa.
