Thanks everyone for the well wishes. The surgery was a couple of days ago and I'm feeling pretty well.
So here is the rest of the story (or at least as far as I can make it before the pain meds kick into full gear).
After I went to the local hospital about the presumed gall bladder attack where they saw the "really big cyst" (RBC), I went to my RE in the big city hospital (BCH). The people at the RE's office were not terribly impressed with the RBC. They said that it looked like a peritoneal inclusion cyst. Well, the narcotics took effect faster than I thought. Before I fall asleep on the screen of the iPad, I'll have to pick up the story later.
