I did have my colonoscopy. I was also able to keep down the nasty stuff they have you drink to clean out your system this time, but this time I had to do it within a few hours instead of half at night and half in the morning.
The colonoscopy showed that my acute diverticulitis was healing, but they also found a couple of places that they took biopsies from. I may get the results this week. They thought it might be one of three things, inflamation, infection, or a slight case of Crohn's disease (reading about Crohn's on WebMD, it doesn't appear that I have the same symptoms, but we'll see what the biopsies say).
