Hi doctor! I had an endoscopy 3 months ago and the results showed that I had a moderate level of inflammation of the entire lining of the stomach and duodenum with no HP. After taking the drug for 3 months, the condition does not go away. Now, I still eat indigestion, belching, choking, burning in the abdomen, especially the right abdomen right next to the hip, and the pain spreads to the back. So the doctor asked me to take medicine for congestive inflammation of the entire lining of the stomach and duodenum for 3 months but still have indigestion, belching, choking on the throat, burning stomach, is it dangerous, how long will it take to heal? and the burning pain in the side is it due to the effect of the stomach and how long will it take for me to have the endoscopy? I hope you can give me some advice, thanks!
