Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you should definitely
consult gastroenterologist and get done upper GI (gastrointestinal) scopy for the diagnosis.
By your history and description, possibility of
GERD (
gastroesophageal reflux disease).
You are also having
cough, this also favours reflux disease.
Along with drugs, you should follow below mentioned lifestyle modifications for better symptomatic relief.
1. Avoid hot and spicy food. Avoid junk food.
2. Avoid
stress and tension.
3. Avoid large meals, instead take frequent small meals.
4. Go for walking after meals.
5. Keep 2-3 pillows under head in bed.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
