Concerned
I too have pelvic pain and have had multiple surgeries. However, have you had the bulge for the entire last 2 weeks? That and the temperature makes me think that you should definitely go see a doctor and get it checked out. You could have adhesions that are binding something somewhere or even a small leak into your abdominal cavity. Please don't wait any longer as this could be something serious and shouldn't be ignored. Let me know how you make out with it. My prayers are with you.
