4. Vomiting
You may blame sudden vomiting on food poisoning or a seasonal bug, but throwing up could be a sign of appendicitis. Although the appendix is a small organ, it can create a host of problems in other organs and the entire gastrointestinal tract. In addition, an inflamed appendix can also affect the nerves and can cause vomiting.
If you are sure that you are not suffering from food poisoning or the flu, which often distinct and familiar symptoms, ask a doctor whether the vomiting could signal a problem with the appendix. This is particularly true if the vomiting is accompanied by a pain on the right side of your body.
