Thanks for writing your query.
After reading your post, it seems that you might be having gastritis
I would advise that you should take an antacid
40mg once a day before meals.
Following precautions will be helpful :-
1.Avoid spicy and oily foods.
2.Avoid being empty stomach for long periods.
3.Avoid mental and emotional stress.
4.Avoid smoking and alcohol, if any.
5.Avoid self medications, especially pain killers and steroids
6.Drink lots of water daily.
I would also suggest that you should get yourself clinically examined and investigated.
will be helpful.
I hope this is helpful to you.
