Welcome to HCM.
From the symptoms you have mentioned, it looks most likely to be Gastro-Esophageal Reflux disease.Consult a gastroenterologist
and get a gastroscopy done to see if you have eosphagitis, gastritis
, gastric ulcers
etc. and according to the finding you will need treatment.
Meanwhile avoid spicy food, liquor, smoking and take frequent small quantities of milk.
Wish you all the best.
