Thanks to everyone for their ideas and advice. She is now back in the hospital again after her stomach started to be distended.
Apparently she has either an ileus or an obstruction. They drained her abdomen today and got over a gallon in fluid out. She is feeling some relief from that thank god.
As for her thrush, they brought over another gastroenterologist today to look at her mouth and throat to make sure that it isn't something other than thrush. I just got off work so I don't know that the verdict is on that.
The gas pain she is feeling in her shoulder is what they call "referred pain"... and she hasn't had any relief... but then again, she has been to weak to move around... hence the lack of relief.
Thanks again... If you have any other advice or insight into any more obstacles she may face, it would be appreciative.
