If it was appendicitis your MD should have checked/known.
Odds are you have accumulations on the walls of the intestines and these ferment/rot causing toxic gases. You also can have ribs/bones/muscles out of place all of which cause organs to not function properly as well as spine pinching nerves, etc. which can cause the valve located near the appendix to not be opening properly, etc., etc.......
The wrong diet causes ulcers by the thousands as shown in the 108 page booklet on my web site.
If you have appendicitis, it will put you down and fever, pains, etc. that will force you to seek medical aid, unless your educated with the natural methods and are willing to try to cure a ruptured appendix at home, which most herbal teachers will tell is not worth it unless your a die hard "I will die before I take another drug" type of person.
Your cure is the diet, plain and simple. Read the website, read what I call BOOK I and if that makes any sense to you, then thats the cure as far as I am concerned. Remove all bad teeth/dental, correct water and stop the poisons, etc.
