I have had GERD for almost two years (Chronice heartburn). I got my gallbladder removed on February 8th of this year. I had no problems and all was well until after I ate Italian food for dinner one night and woke up with bad stomach/esophagus burning and so I took 4 Tums and went to bed. I ever since have been having the burning pain that feels like a gnawing& burning pain 24/7. Even on my maximum dose medications for my GERD it is still there. It has not gone away for one second of one day. My doctor wants me to see a gastroenterologist and prescribed me Carafate, but has to talk to my insurance and have me get a professional opinion.
My dad has these issues with heartburn too. I've asked him to stay away from anything with acid, especially pasta sauce, anything with acidic vegetables, sodas, coffee, and wine. Also eating after 6pm makes it worse. If this happens at night again, prop yourself up to sleep and use a neck pillow (not tucked behind your head) to catch your neck. Tums are helpful but too many can be harmful. I hope your doctor finds clues to help you.
Wishing you hope & healing,
Cindy
