Hello,
There are two possibilities, first one is
acid reflux disease and other is allergic.
Do you also have upper
abdominal pain, nausea,
bloating, burping, increase in pain on food, sour water feeling in throat or chest burning, these are the other symptoms and may be associated.
You should try avoiding fatty, oily and spicy diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Lots of green leafy vegetables, fruits. Avoid
smoking and alcohol if any. You can get prescribed tab Pan DSR 40 mg or esomiprazole
domperidone combination beforebreakfast once a day for 2 weeks.
Do you also have any allergic symptoms like running nose, blocked nose, itching over body etc, if yes you should have tab Montair LC bedtime for 2 weeks.
Hope this helps you and get back if you have any doubts.
