Welcome to HCM.
It is difficult to diagnose without examination, based on the information provided it appears to be GERD
I advice you to avoid spicy foods, smoking
and alcohol. You can take over the counter medication
to reduce the acidity and also Proton pump
inhibitor once a day early morning empty stomach for 7 days.
Even after the above mentioned approach symptom persists i advice you to see physician for examination and for exact diagnosis.
Hope I have provided the information you needed.
Wish you good health. Take care.
