Hello. Welcome to hcm.
You might be suffering from gastritis
. It is a condition where the acid secreted by stomach causes severe burning sensation. It might be due to simple oily foods taken or due to infection by H.pylori.
I advice you to stop taking oily or spicy foods. You should start taking tablets called proton pump
inhibitors namely omeprazole
and you need to be evaluated for infection or cause of gastritis and treated accordingly. Try to have minimal food every 2hrs so tat you wont be with empty stomach.
All the best
