i am only 2 weeks post-op but I am getting the same thing it has only happened 3x but I think i ate mash potaotes really thin but I guess not thin enought and soup with pastina and it happened then. I am associating it with food differences, But it really hurts and I do sweat I think because of the pain. Today it happened and I am not sure why this time. but a couple of hours a some good belches and I felt better
