The symptoms as mentioned by you suggest that you might be having Gastroesophageal reflux disease
, which is caused by the reflux of acid from stomach to esophagus due to relaxation of the sphincter at the lower part of esophagus.
Medical management consist of taking Proton pump
inhibitors like Omeprazole, Pantoprazole
,etc. (which prevent acid formation in stomach)
can also be used but it has some side effects on long term usage.
Also avoid consuming irritating substances such as acidic & rich foods, caffeine, nicotine, and alcohol.
Try to sleep on the left side, or with your upper body raised.
If symptoms still persist, it will be better to consult a Gastroenterologist
There is no need to worry...you will be fine.
Wish you a good health & speedy recovery.
Thanks & Take care.
