What is a classic symptom of appendicitis?

Right lower quadrant pain is a classic symptom of appendicitis due to the anatomical location of the appendix, which is situated in that area of the abdomen. When the appendix becomes inflamed, it typically causes localized pain in the right lower quadrant. This pain often begins as a vague discomfort around the umbilical region (periumbilical) and then shifts to the right lower quadrant as the inflammation worsens and irritates surrounding tissues, including the peritoneum. This movement of pain is known as "referred pain" and is a hallmark feature in the diagnosis of appendicitis.

While other symptoms mentioned, such as fever and chills, can accompany appendicitis, they are not specific to the condition. Left upper quadrant pain and epigastric pain are indicative of other abdominal issues, such as splenic or gastric problems, rather than appendicitis. Thus, right lower quadrant pain stands out as a key and characteristic sign that healthcare providers look for when evaluating a patient for potential appendicitis.
