Additional info. Went to the PCP today to followup, explained the entire event. He put the scope to different parts of my chest, and then said, "I can hear your stomach in your chest. I think you have a hiatal hernia. When I mentioned the meatball sandwich I had mid-ride, he asked whether it had had tomato sauce. Yes it did. I always ask the guy for lots of extra tomato sauce.He said that'll do it. Advice is to take Protonix until things heal, lose some weight, go from there.
