Hi. Thanks for your query. Read and understood your history. This is a typical history, where the person suffers from pain in abdomen for 2 days after eating chicken. Starts as stomach ache and then increases in intensity followed by dizziness and fever. -No pain by day 3. - wonderfully appendicitis relieved your pain for 2 to 3 years. This is fare and odd to notice. Usually the symptoms would have been not relieved at all or wound not have recurred. I would advise you the following: The simplest tests are: It is you and your family members who have to list down everything you eat or drink and see what are the foods and / or beverages that are causing the problems you have. -In addition I would advise also to have one colonoscopy so that a certain problem related to colitis can be confirmed or ruled out. The treatment obviously is to avoid , in fact say no to all the foods / beverages / spices / additives/ adulterants which you must have noticed to cause you a problem like the one you explained so well.
