How did GERD start for you ?

I am asking since I am curious. Was it suddenly like you got acid refluxes out of nowhere ? I got my first acid reflux this week and I had Globus sensation and regurgitation that’s it and got chest pain eventually after I unknowingly had spicy food because of a miscommunication. The acid stayed there for 2-3 days but with omeprazol and antacids it wasn’t bad. The second time is 2 days after I had my last one with again Globus sensation and regurgitation but it was gone I couple of hours and it seems to be triggered by eating to close to bedtime. My doctor said I may not be GERD or they cannot diagnose it yet, which I get but this makes me curious on how you guys got GERD.
