Thanks for your query.
I will try my best to provide you with best possible professional recommendations to your questions.
Your symptoms are suggestive of gastritis
contains NSAID which it self can cause gastric discomfort.
I advice to avoid spicy food and smoking
, alcohol for few days.
I advice you to take proton pump
inhibitors which will decrease the acidity and relieve your symptoms.
You have to take the drug twice a day 1/2 hour before consuming food.
Also you can take antacid
syrup. You should consume this drug for 7 days.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further query.
