5. A high fever
Just like the body purges itself whenever it is infected by a foreign pathogen, it also raises its temperature. A fever is the body’s way of trying to create a less hospitable environment for the infection. Since appendicitis is an infection of the appendix, a fever is a very common symptom.
This fever will be high, too; above 100° F., A fever can worsen other symptoms. For example, as your fever rises, the urge to vomit will become worse. A fever is a common symptom of several other medical conditions; however, if you are experiencing intense abdominal pain and you are vomiting, it’s highly likely that you have appendicitis.
