A general queasiness, or feelings of nausea. One of the most misleading symptoms of appendicitis is queasiness or nausea, and as the condition progresses, even vomiting. While the intense pain associated with the disease may worry a person at first, once nausea and vomiting set in a person may convince themselves that they have little more than a stomach infection. This is exceedingly dangerous since appendicitis is almost always fatal if left untreated. This is why you need to view the symptoms as a composite whole and seek medical assistance before the condition becomes life-threatening.

Running a temperature. Appendicitis is a serious infection, and as the body fights it, it is inevitable that the patient will begin to run a fever. In the initial stages of the disease, this symptom might mislead a patient into thinking he or she is suffering from some sort of flu. However, the fever will continue to rise to dangerous levels as the condition progresses, and other indications of the condition will also intensify.

Shivering. Patients suffering from appendicitis often experience intense bouts of shivering, and “feeling cold” along with the fever that is an obvious symptom of the disease. The shivering that one experiences are the muscles undergoing contractions in rapid succession as a means to healing the body. In appendicitis, as with most infections, the fever is an indication of the body fighting the infection.
