Dear doctor, about a week ago, about 1am to 2am I woke up because of upper abdominal pain. After that, I had to drink a glass of milk or eat cereal, and sit for about an hour to get better. So doc, what's wrong with me?

Hi doctor! On August 25, 2019, I had a gastroduodenal endoscopy with 03 hyperplastic polyps 2-3mm in diameter, it's been almost a year now.
