About two weeks ago I woke up and found that I couldn’t keep anything down. Since I know so much about medicine (NOT), I diagnosed myself with a stomach bug and curled up into a ball, waiting for the pain to go away. It didn’t. It got worse, in fact, and so after another day I called a nurse friend and asked for advice. She suggested that I was suffering from something far more dangerous than the flu -- appendicitis -- and she made me promise to go to the local emergency room. So I did. She was right. She probably saved my life.
