I think you should have it checked out if you feel something might be wrong, unfortunately I had to have a referral and my primary Dr. didn't think I had enough to go off of, but i knew something was wrong, my band had slipped around my esophagus and I couldnt even keep water down, we had been moving, but anyways I think it is a good idea to have it checked out and it was expensive to go out side my insurance because they want to do an upper GI and a Barium swallow and with no insurance to cover that it is expensive. Don't get me wrong and worry if you haven't seen a Doctor in awhile, I love my band and I want it back. thanks for your post.
