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.
In many cases, the cause for appendicitis is unknown. There can also be multiple causes for one case of appendicitis. Doctors believe an obstruction in the appendix may cause appendicitis. Obstruction may be either partial or complete. Complete obstruction is a cause for emergency surgery. Obstruction is often due to an accumulation of fecal matter.
