Hi, thank you for posting.
I have gone through your query and I understand your concerns.
Your symptoms are suggestive of Gastroesophageal Reflux Disease(GERD).
-You should eliminate spicy foods from your diet.
-Do not drink alcoholic drinks, carbonated drinks, milk and coffee.
cigarettes(if you do smoke).
40mg is also recommended.
However to confirm the diagnosis you need:
3. Complete blood count
5. Urine test.
Consult your gastroenterologist.
I hope I helped you.
All the best.
