Hi Jen,
I was banded 3 years ago and about a year out I started having occasional, out of the blue episodes of "heart attack like" pain that would radiate into my jaw. Very scary, but it turned out to be esophageal spasms. I also have been having lots of heartburn. Recent tests (upper GI with barium) show that I have a slip. Having a revision tomorrow a.m. Not happy about it but I look at it as a new start. Try not to worry, just do what you have to do to be healthy and pain free!
