Thanks for your comment. I have researched LPR and GERD for two years, using sites like https://jamiekoufman.com. I am on a low acid, whole food diet as outlined by another ENT, Aviv. So I know a lot but the origin of the chest pain is the remaining piece. If it's a spasm I wouldn't care as much as I would if it were the stomach coming thru the hernia. In any case the number of incidents is much lower than it has been, and I have a system in place to mitigate the pain while doing exercise. If it happens while I am sitting or in bed I move until I find a position where it goes away. I wish you well.
