I have been having pain in my right side , off and on since my appendectomy 3/13/12.  I have had 4 Cat-Scans and one colonoscopy with another scheduled in one week and my surgeon says I have an ulcer where the appendix was.What should I be worried about?
HI. First I would like to know the age, as the diseases are different for different age groups. The ulcer can be due to many diseases for which only biopsy can give a definite diagnosis.
