One year post appendicitis that was treated with antibiotics, not surgery: a few times a month the area where my appendix was (was told it was so bad that it "probably turned to goo") i get a pain. it is sharp but short lived. cause for concern?

Doctor can evaluate: Lower right abdominal discomfort can be from many things. For pain there, appendicitis is always a concern (pain usually worsens over time, with fever coming on). If one is constipated for several days, stool can back up all the way to the right side. Gallstones, kidney problems, and ovary issues can cause pain. A primary care doctor or a general surgeon can examine. An imaging scan may be needed.
