I had no symptoms at all of appendicitis, none. No pain, no fever, and no diarrhea. As far as I was concerned I was a healthy patient. I had kidney pain on my left side and had a CT scan looking for kidney stones, no stones were found but they did find an inflamed appendix. After consulting with my surgeon I had it removed, started with laparoscopy but the appendix was so swollen they couldn't stitch me back up well.
The first symptom of appendicitis is usually nausea, then pain or a vague, uncomfortable feeling around the navel. Things often go downhill rapidly from there. In acute appendicitis, intense pain builds in the lower right side of the abdomen. Many people also experience a loss of appetite (anorexia), vomiting, a feeling of tenderness in the abdomen, or a slight fever. In some people, the appendix sticks out in an unusual place or an odd angle. In these cases, appendicitis can cause other symptoms such as pain in the sides or the back, pain during urination, or pain in the upper left side of the abdomen. If you have these symptoms, go to an emergency room immediately. Appendicitis is a medical emergency.
