In appendicitis, where is pain often first felt before localizing?

In cases of appendicitis, the initial pain is often experienced in the periumbilical region before it localizes to the right lower quadrant (RLQ). This phenomenon occurs because the sensation of pain from the appendix is transmitted through visceral nerves that communicate with the abdominal wall and internal organs. The first point of pain is typically generalized and felt around the belly button, which is associated with the initial inflammatory process affecting the appendix. As the condition progresses and irritation of the parietal peritoneum occurs, the pain then shifts and becomes more localized to the RLQ, where the appendix is situated.

While the pain may sometimes be perceived in other areas of the abdomen, the defining characteristic of appendicitis is the migration of pain from the peri-umbilical area to the RLQ. Thus, understanding this pattern is essential for recognizing appendicitis and distinguishing it from other abdominal conditions.
