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 gastritis
I advice you to avoid spicy food, smoking
and alcohol. You can take Proton pump
inhibitor which will reduce your acidity, this drugs should be taken 1/2 hour before consuming food.
drugs are taken twice a day one morning and other in night for seven days
Also i advice you to take antacid
After seven days if the symptoms will not subside, i advice you to see surgeon, upper G I endoscopy
will be helpful for coming to diagnosis.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further query.
