Chronic appendicitis doesn’t necessarily cause hidden pain every day. Most people with chronic appendicitis have frequent vague abdominal pain, but few have vague pain every day. Most patients may also experience intermittent pain or no pain at all. The appendix is located in the lower right side of the abdomen, so most patients with chronic appendicitis tend to present with a vague pain in the lower right side of the abdomen when pain manifests. It may also not be felt if the patient’s pain sensation is dull. However, during an acute attack of chronic appendicitis, there will be hidden pain in the lower right abdomen. Frequent pain in chronic appendicitis is also detrimental to physical and mental health, and can lead to intestinal adhesions. Therefore, once chronic appendicitis is diagnosed, it is recommended to give intravenous ceftriaxone sodium, levofloxacin, ornidazole and other antibiotics to fight infection. After the inflammation subsides, elective surgical resection can be performed to completely eradicate chronic appendicitis. Drugs should be applied under the guidance of a doctor.
