Well, I tell ya guys and gurls, that pain is probably coming from your diaphram, it can hurt for quit some time after WLS. This info I got from my Surgeon. Also if you eat to soon, or to much it can also make you hurt. The gas they use to "blow you up" with can also make you hurt for some time. I was told, walking and a heating pad will help a lot. It has nothing to do with the size of your band.
Hang in there, as time goes by it will all feel better.
