On October 8, 2020, I went to the hospital for a gastroscopy, the doctors concluded that I had gastritis and gave me 2 oral drugs, the first is Sotig 40 taken 1 hour before eating, 1 tablet taken 2 times a day, The second is S-cort rebamipide 100mg orally twice a day after meals. Please advise why I have abdominal pain after taking Sotig 40 to treat gastritis? Thank you doctor.
