What are the symptoms of appendicitis?

Appendicitis presents with the following main symptoms: 1. **Abdominal pain**: Initially, pain occurs in the upper middle abdomen or around the navel, later shifting and localizing to the lower right quadrant of the abdomen after several hours—this is known as migratory right lower quadrant pain and is a typical symptom. 2. **Gastrointestinal symptoms**: Commonly accompanied by nausea, vomiting, abdominal distension, diarrhea, and some patients may experience a decreased appetite. 3. **Systemic symptoms**: Fatigue may appear early in the disease course, followed by fever as the condition progresses. Body temperature may reach above 38°C and, in severe cases, may exceed 39°C. 4. **Physical signs**: Significant tenderness at McBurney's point in the right lower abdomen is observed, often accompanied by rebound tenderness and abdominal muscle rigidity. Appendicitis manifests with a variety of symptoms, the main characteristic being migratory right lower quadrant pain, accompanied by gastrointestinal and systemic symptoms. Prompt medical attention is necessary for diagnosis and treatment.
