First the pain need to be ruled out whether it's only gastric related or any other issue is involved too. For time being take food with less masala  and chilli powder. Avoid foods which causes indigestion or acidity for you. Take  one Tablet Pantodac 40mg half an hour before breakfast in the morning. Continue this for 20-30 days . There is no harm in taking this tablet for few months too so you don't worry about it. Contact me through  direct chat consultation if you have further queries. Thank you
