I agree with the Barium swallow. It shows the most for the least pain. The rest aren't fun, and I personally hated them so much I wouldn't push them. But that's me.
It's still plenty early and you could still be healing. I got off PPIs after 2 weeks, but lots of people never do get off them.
Did you have a full wrap? Maybe it was just done too loose. The barium swallow will show if there is any reflux going on.
Have you had any vomiting or done anything that caused serious pressure to the abdomen? That's about
all I can think of that could loosen a wrap that was done right.
This isn't an exact science. Everyone reacts differently. Best wishes!
