I had surgery on 6/7/12 and have had a pretty easy time of it till now. My first fill was uneventful but I have recently had my second fill of 2 cc ( total of 8 cc in a 14cc band). I notice when I go to eat or drink it feels like I have air in my stomach and have the need to burp but cant. This takes several minutes to resolve itself and on some occasions if I try to push past it causes a blockage that created pressure in my chest that is painful. What am I doing wrong?!?!?
