The typical symptom of appendicitis is pain in the lower right abdomen. Generally, during acute appendicitis, the pain can last for several hours or even longer, with about 70% to 80% of patients experiencing characteristic migratory pain in the lower right abdomen. Migratory pain in the lower right abdomen refers to initial pain in the upper abdomen that later manifests as persistent pain in the lower right abdomen. However, some patients initially present with pain in the lower right abdomen directly. In some cases of pregnant women with acute appendicitis, due to the appendix being pushed upward by the enlarged uterus, pain can also occur in the upper right abdomen. Additionally, acute appendicitis is often accompanied by nausea, vomiting, abdominal pain, and diarrhea.
