Persistent Burping After Bariatric Surgery: Causes & Solutions

Question
I burp constant, and have since the beginning. I had surgury Dec 5, 2006.  It has gotten so bad that it has started to affect even my back.  I can't even drink water without burping.  I have tried all kinds of ant acids with NO help.  I have tried a round of very expensive antibioitcs, I have had mobility test taken, barium test taken, even a test to see if my stomach empties too fast.  Noting comes back.  I need help badly.  Please let me know what I have to do.

Thank you

Answer
When you say it has started to "affect" your back, what do you mean?  Have the tests you've had been initiated/suggested/ordered by a physician specifically to identify the cause of the burping?  What types of barium tests have you taken?  Have you had a full set of Upper Gastro-Intestinal tests?  I'm sorry that all I have is questions, but I am not about to suggest anything without having this information first.
