I was getting sick all the time too, has she had radiation? When I had radiation it affect the area between the esophagus and the stomach. It actually made it close. the need to do a scope to see what is going on with that. I have had relief after suffering for 8 monhts, and no doctor knew what to do. I went back to my GI doctor that did the scope to begin with and he knew right away to do a scope and check it out. Two weeks later they had to scope me again because it was beginning to close, but now is doing much better
Good luck!!
