I had my appendix taken out 10 days ago. I went in for the follow up visit with the surgeon on Friday and he said it was gangrene. It did not rupture. I am a 35 year old female in excellent health- only prior operations were c-sections and tonsils. I never get sick! Telling me it was gangrene really bothered me. The doctor said pretty much the cause was just bad luck. I asked if anything else was gangrene that he noticed and he said no. I asked something else could be and he said I would be in a lot of pain if there was. Truthfully, I wasn't even in that much appendix pain -- so I must tolerate pain well. I am in such shock that I had something gangrene inside of me! So my questions are this:

How long does it take for something to become gangrene?

Should I follow up with more internal tests to make sure I have nothing else in there that is gangrene?

I was only in pain for a day prior to the surgery. If something else is gangrene will I only know at the very last minute? Or is there something I can do now?

Thanks for your help.
