Sorry to hear that. Did you see a gastric doctor as well? if the surgeon says nothing can be done, then he would refer you to someone. Ice numbs the pain, but the inflammation doesn't go away.
I had a hiatal hernia too. It's naturally formed and not caused by trauma. I am not even sure if it has something to do with my acid reflux, I believe my lifestyle contributes more (I have a stressful job).
I see my Gaso surgeon Friday. The ER I went to took scans of my 2 visits and sent them to this doctor. Wish me good luck.
