Hello History of stress and stomach pain on eating might be related to Duodenal ulcer or acid peptic disease due to stomach hyperacidity I see patients with similar complaints in my clinic and I would advise them to take pantoprazole or ranitidine group of drugs with antacids or syrup sucralfate for 3 to 5 days You should avoid spicy food and hot and junk food. Complete abstinence of alcohol and smoking Avoid stress and anxiety and remain cheerful If it doesn t improve with these than you should consult a gastroenterologist for an endoscopy and further evaluation If you can write back to me with your age and complete medical history so that I will be able to tell you more accurately. Best wishes
