Thanks for your question on Health Care Magic.
I can understand your concern.
Since your
stress test is negative, no need to worry for any major cardiac diseases as a cause for your chest fluttering.
In my opinion, your symptoms are mostly due to uncontrolled
GERD (
gastroesophageal reflux disease).
You need to follow certain lifestyle modifications along with drugs to control GERD symptoms.
So avoid stress and tension.
Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals.
Quit
smoking and alcohol if you have these habits.
Go for walk after meals.
Keep 2-3 pillows under head in the bed to prevent reflux.
With all these and drugs, you will definitely improve.
Hope I have solved your query.
Wish you good health. Thanks.
