Amy, I'm sorry you're having this tremendous stress. (not good for your tummy). I would be having a panic attack too. Maybe it's not a hernia afterall. Let's pray for the best and see what happens.
When the back doctor told me my X-ray was abnormal, I freaked out too, worrying about cancer and all kinds of horrible things. I was relieved once I had the test and had an answer to what was causing my pain. Not knowing is the worst thing!!!
When are you having the test done? Hopefully, you won't have to wait long.
