The location of the appendix is different for each person and the abdominal pain that occurs is also different. A high appendix may present as right lumbar pain, while a low appendix has lower abdominal cramping pain. The variation in the degree and location of abdominal pain often causes acute appendicitis to be misdiagnosed as other diseases, especially in the elderly and pediatric patients. Patients with appendicitis may have nausea, vomiting that stops 1 to 2 times, and symptoms such as loss of appetite, bloating, diarrhea, etc. Some patients have fever, headache, general weakness, and increased total white blood cell count in laboratory tests. The characteristics of pediatric acute appendicitis are not uncommon in children. 4-5% of the cases are under 12 years old. The onset of the disease is often preceded by a cold, tonsillitis, diarrhea and other triggers, manifested as chills, fever, nausea, vomiting and diarrhea, the location of abdominal pain can be in the right lower abdomen, around the navel or the whole abdomen, careful examination of the abdomen, but still the right lower abdomen pressure pain is obvious.
