There's good news and bad news...
The good news is that the relapse happened in the hospital. The bad news is that things reversed themselves, and the previously optimistic prognosis is more guarded. I spoke to the doctor this afternoon, and they are hoping for surgery tomorrow to anchor the stomach so it doesn't decide to migrate back north and wedge itself into the diaphragm again. As most can imagine, the pain of this occurring is quite marked, being a 10 out of 10. Within a few hours (even 2 minutes like this is too much, of course, but they did the best they could), the pain was much lower, and they are hoping for the stomach to descend on its own.
Still more watching and waiting.
