Hello @alexaadams, Welcome to Connect. I'm sorry to hear you are having to deal with complications following your laparoscopic appendectomy. It's great to hear that you have an upcoming appointment at Mayo Clinic to figure out what is causing the terrible symptoms. While we wait for members with experience to join the discussion, I did find two references on the topic.

--- Recurrent Abdominal Pain after Laparoscopic Appendectomy: https://synapse.koreamed.org/articles/1007626
--- Recurrent pain abdomen following appendectomy: Stump Appendicitis, a surgeon's dilemma: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5331228/.

There is a similar discussion here that you might want to read through.
--- 3 months after appendectomy: https://connect.mayoclinic.org/discussion/3-months-after-appendectomy/

Can you provide an update after your Mayo appointment?
