Had an appendectomy, but am currently experiencing the same symptoms as during my appendicitis. not sure what to do.

Good place: To start would be your surgeon who performed your operation. It is possible that you have another condition, such as ovarian cyst, pelvic infection, crohn's ileitis, cecal diverticulitis, kidney stones, etc. Your surgeon will help you figure it out for you.

See your surgeon....: Was your surgery recent? Pains or illness after surgery, especially after what was likely an emergency surgery for you, needs to be addressed by your surgeon. Contact your surgeon to ask questions & make an appointment for evaluation. However, if the surgery was more than several months ago, then see your primary doctor or go to an er to be evaluated.

See your surgeon: Go back to your surgeon and be re-evaluated to make sure there isn't anything wrong with your surgery and to re-evaluate your present symptoms.
