As soon as I got done posting that last one, the doc came in again and I got to hear first-hand. They're taking this pretty stinkin' seriously. So they are drawing her blood now, then they're going to put some contrast into her NG tube (she doesn't have to taste it...blessing), then send her off for the CT scan. They said they are concerned about a blood clot in the lung and if they find one, they will take her directly to surgery because it's life-threatening. The CT scan will also show if she does have pneumonia. They also said that there's the possibility that nothing is wrong except the bowel obstruction and they're on the right course with the NG tube.
I don't know if I realized how serious this was... please, please pray.
If you don't pray, get saved, then pray! (No, really, you won't regret it)
