Detailed explanation-1: -Visceral pain is experienced when the walls of an organ are stretched and the nerves send signals to the brain. Due to the lack of nerves, the pain is poorly localized and often described as an ache or cramp. Parietal pain is caused by irritation of the peritoneal lining that surrounds the abdominal cavity.

Detailed explanation-2: -The main symptom of appendicitis is abdominal pain. This is initially peri-umbilical, classically dull and poorly localised (from visceral peritoneum inflammation), but later migrates to the right iliac fossa, where it is well-localised and sharp (from parietal peritoneum inflammation).
