Hi, Welcome to HCM, It seems that you might have acute Gastritis or hyper acidity causing this problem. There is also a chance of having gastric ulcer. Go for sonography of upper abdomen to rule out gastritis and gastric ulcer. Avoid fried,chillies and junk food. Take milk diet,buttermilk,curd,rice. Mean while take Omeprazole daily. Quit alcohol or smoking if you have habit. Avoid stress. Ok and bye.
