Thanks for your query.
I will try my best to provide you with best possible professional recommendations to your questions.
I think you are suffering from Acute gastritis
I advice you to avoid spicy food, alcohol and smoking
for few days. Consume less spicy food like milk, curd rice or butter milk are good.
You can also try over the counter drugs like antacid
syrup or H2 blockers , PPI to reduce your symptoms.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further query.
