Appendicitis: It means that the appendix in the abdominal cavity is diseased. Appendicitis symptoms: 1. Metastatic right lower abdominal pain. Typical acute appendicitis, at the beginning, abdominal pain is mostly around the middle and upper abdomen or navel, and patients can't accurately identify the exact location of pain. After several hours or more, abdominal pain moved to the right lower abdomen and the pain persisted. About 70 ~ 80% patients have the above-mentioned abdominal pain history.

After the onset of appendicitis, there is an obvious tenderness point in the right lower abdomen, which is also the most important feature of appendicitis.

4. Systemic symptoms. Once the disease occurs, it is often accompanied by symptoms such as dizziness, headache and fatigue. If the condition is serious, there will be symptoms such as fever and palpitation.
