Describe the classic pain of appendicitis.

The classic presentation of appendicitis typically begins with periumbilical or epigastric pain that eventually migrates to the right lower quadrant of the abdomen. This pattern occurs due to the irritation of the peritoneum by the inflamed appendix. Initially, the pain is often described as vague and difficult to localize, which can lead patients to report it near the umbilicus or upper abdomen. As the condition progresses, the pain becomes more localized to the right lower quadrant, where the appendix is situated, leading to a stronger and sharper sensation of pain there.

This progression of pain is an important clinical feature that aids in diagnosing appendicitis. Understanding this symptom pattern is crucial for healthcare providers, as it distinguishes appendicitis from other abdominal conditions that may present with pain in other locations, such as the left lower quadrant.
