I had the same tests done that you've recently had. I had the same thing happen with my barium swallow test.
When the guy told me he did not see a hernia, I got upset and posted about
the experience on here. This is the link to my post.
Denise suggested I have what is called a "sliding hernia," and it turns out she was right. When I saw the surgeon a second time I talked to him about
my concerns. He explained that in the barium swallow test, your hernia may be too small and actually slide up and down at times to where the test cannot see it.
