The same exact thing happened to me in march of 2023. The only thing different is I started taking papaya enzyme tablets after eating. I'm 70 years old with a history of stomach problems ( stomach obstructions, ulcers, bleeding ulcers) and it's very scary feeling when gerd happens. Hopefully for you it heals up. I had endoscopy shortly after it healed and the doctor said it looked good and didn't need stretching. It's been good since (n.o.w.). I have been on protonix and pepcid for a long time and the only thing different is that my doctor put me on a low dose of paxil for anxiety. The hardest thing was giving up coffee, I now drink tea.
