When I had to have my appendix out, the doctor had no idea what was wrong. All of my tests kept coming back inconclusive and he didn't think I was in enough pain. His suggestion was to go ahead and take my appendix out since we don't need one and then he would do exploratory surgery to figure out what was wrong. It turned out that my appendix was about to rupture so he didn't need to do anything else. But I actually agreed to the exploratory surgery initially just to figure out what was wrong. I appreciated his honesty with me. Sometimes, when nothing else fits, exploratory is your only option.
