Let's recap the symptoms: Abdominal cramps, nausea, distention, tenderness in the lower right quadrant, and elevated WBC count.
Dr. Packrat diagnosed appendicitis. Hospital diagnosed pneumonia.
Turns out I was closest. Her Primary Care Physician indicated it was either colitis or diverticulitis. THAT fits the symptoms a heck of a lot better than pneumonia.
This does not say much for the quality of care at the local hospital...
