It is possible for mild appendicitis to heal on its own within a week or so with good care, but the odds are not good. Appendicitis is an infectious disease that should be treated aggressively. Appendicitis is usually caused by a bacterial infection or a blockage in the lumen of the appendix, causing pain in the lower right abdomen. If the patient’s resistance is strong, it is possible to recover within a week or so with proper care. However, if left untreated, the patient’s resistance decreases, which is more likely to cause aggravation of the disease, resulting in fever, chills, and severe pain, and the patient should be actively treated. Acute simple appendicitis needs bed rest, during the attack should be fasting and water, under the guidance of the doctor to use metronidazole combined with ceftriaxone and other antibiotics for treatment. After the inflammation is under control, patients can have their appendix removed surgically. Appendicitis must be timely to the hospital for treatment, to avoid the development of aggravation of the disease.
