Some people with chronic appendicitis may only feel fatigue and mild pain in their stomach. It is natural to confuse this condition with a common stomach flu or virus. If discovered in time, it can be treated with powerful antibiotics, saving the patient the need to undergo surgery. Just because it takes longer to recognize the symptoms, does not mean chronic appendicitis should be taken lightly. Fever, intense pain and nausea are generally not the symptoms of chronic appendicitis; therefore there is a big chance that it might go unnoticed. Due to the slow progress of chronic appendicitis, you will find that infection may spread all over the abdominal area. The symptoms often vary from patient to patient; therefore, only a doctor can diagnose it correctly.
