Appendicitis that isn't appendicitis mystery!?

I'm surprised they didn't just take the appendix out. I had a friend once who had pain exactly like you are describing and they did exploratory surgery cause it got to the point where no one could figure it out. they had tested her many times for appendicitis and the tests always came back negative, but during the exploratory surgery they took the appendix out, she woke up and the pain was completely gone. They ended up testing the appendix for inflammation and it was apparently very inflamed..Maybe this is the case for you, were it doesn't seem like it is appendicitis, but it actually is..
