My appendix! I started having pain on Tuesday and I really thought it was either an ovary cyst or right-sided diverticulitis. Tried to wait it out, but cried UNCLE yesterday. Went to the E.R. and had a ct scan, and there it was.....a big inflamed appendix! I couldn't believe it. They took it out by endocscopy that evening. I stayed the night and am home again. YAY! It doesn't happen very often that I have a pain that can be taken away. I'm happy. (and sore).
