Thanks for your question on Healthcare Magic.
I can understand your concern.
First of all no need to worry for cardiac
chest pain as your ecg is normal.
GERD (
gastroesophageal reflux disease) related symptoms is more likely because your upper GI (gastrointestinal) scopy is suggestive of reflux disease.
Smokers are more prone for reflux.
GERD needs lifestyle modifications along with drugs.
So follow these steps for better symptomatic relief.
1. Quit
smoking as soon as possible.
2. Avoid hot and spicy food.
3. Avoid large meals, instead take frequent small meals.
4. Go for walking after meals.
5. Loose weight if you are
obese.
6. Avoid
stress and tension, be relax and calm.
7. 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.
