Had surgery Jan. 26, 2011, I can't sip water with out it gathering in the stomach, following back pain, then coming back up. The day after the office removed 2.7 from the port. Allowed me to drink for several hours, before blocking back up. Went to the ER last night, was given a cat scan, which showed that every thing was in the right place, but that I had no fluid passing through. They gave me 2 IV bags, an injection for inflammatory problems and told me to not drink till 7am today. Problem is back, no passage. I'm so thirsty. Has anyone experienced this and what should I expect?
