YES!!! I have experienced this. sometimes the pain is so bad it takes my breath away or feels like i am having an heart attack. What I did for my Hiatal Hernia was to visit a natropathic physician. The stomach moves up through the enlarged passage in the diaphram into the thoracic cavity. Not all the way all the time but it has the potential as I have felt. Any how my natropath pulls my stomach down manually and oh what a relief. She also helped me with my diet so I rarely have acid anymore. It has been almost two years since I first saw her and I can count on one hand the number of times I have felt the pain and hardly anymore acid. I would suggest you do the same. Or see a chiropractor who has treated hiatal hernias before. Feel free to email me. Good Luck.
