Majacw, I went and had a complete unfill and an xray right off. Nothing showed up. My doctor scheduled me for a barium swallow. In the meantime, I still had some restriction with the complete unfill and was still having pain. I also developed heartburn-burning in my lower stomach, no reflux. Went for the barium, no problems showed up there either. Next I went for an EGD (endoscopy). My surgeon does the procedure himself. He found no erosion.
I'm stil having the same problems and no matter what anyone else believes, I still think there is some issue related to my band. I've read over and over how things were missed or did not show up on tests and problems ended up being band related. For now I guess I will just wait and see what happens. I can eat fine, managed to lose 10+lbs since I began having issues.
Hopefully down the road it won't end with some emergency situation. Other than exploratory surgery I don't know any other steps my surgeon could have taken.
Please let us know how your appointment goes. I hope they can straighten things out for you without putting you through too much!
