I had the same problem over the weekend, the tech could not get any Fluid out of my band, and I've not been able to get solid food down since last tuesday, and barely any Water. He tried twice, and I'm sure he got in the port, you can just tell by the pressure and such. Don't know what will happen now. Still no solids for me! I only have 5cc and have been there for at least a year, not losing much anymore, but not gaining either, so happy with it.
As an aside, I really would not recommend for people to have the doctor take all the fluid out, then add to it when having a fill. I personally am very very sensitive to the change in restriction with the band. When the one surgeon does a fill on me, he does this, and I am so tight for a week from swelling. When the other surgeon does a fill, he just adds to what the chart says, and I am fine. I finally figured out this is what the problem was after a couple of fills by different people, and different reaction to each. Sometimes I was so tight and swollen I would have to come back the next day and have it all back out again.
