so worried/scared

So last week I had all my fluid removed after having a terrible episode of vomiting and acid reflux (have had several of these episodes that will follow a period of being able to eat freely with no restriction and then out of the blue complete restriction= likely going on since nov but I didn't put two and two together and thought this was just how the band was supposed to work). The did a partial removal of fluid but when I drank water it gurgled down so we just decided to remove all the fluid as the dr. thinks that maybe I dilated/stretched my pouch. I have been on a liquid diet for one week and will be on mushies for two weeks until I go back for a barium test to see if my pouch shrank. My fear at this time is that my port seems to start to stick out and hurt if I drink too much- not at a time necessarily but a quantity over a long time. What would cause the port to be so painful- does anyone understand the mechanics of this? The fluid should go down my throat and easily through the band- which is appears to do- and then into my stomach- what is causing the pain in the port area?
