I had the same feeling and I was banded 11/17/09. For several days I just had a pain up under my heart. Finally at a store I had a huge- huge manly burp come out! It felt so good but it was very noticed by other shoppers. Now when I have to burp -it just comes on no warning and they are loud. All I can do is cover my mouth and hope no one is around. It really relieves that pressure under the heart.
