The appendix may also be on the left side, although normally it is located at the junction of the ileum and the cecum, and its position is mainly in the right lower abdomen, but in a small number of patients with a long appendix, a part of it will be located on the left side of the abdomen. There are also a small number of patients who are mirror people, meaning that the entire position of the organs in the body are aligned, and there will be an appendix on the left side of the abdomen. Therefore, when there is obvious pain in the abdomen, you need to go to the hospital as soon as possible to improve the relevant examination to clarify the cause of the disease, usually need to check the blood routine, C-reactive protein, abdominal ultrasound, abdominal CT and so on. If appendicitis is considered to be the cause, first of all, we need to give antibiotics for treatment, improve the relevant examination, and perform surgery to remove the appendix. During the treatment period, the patient should not drink drinks containing alcohol and should not eat spicy food.
