I was just recently banded on 9/15/08 and I went through the same thing. It is normal for you to have trouble burping along with the gas in your chest. I actually went to the ER the pain was so bad. Just be sure to walk every hour around your living room for as ong as you can. My chest pain finally subsided after 1 week and a 1/2. You will be fine and congrats on your weightloss!!!!!
