Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of GERD (gastroesophageal reflux) is more.
But better to get done ecg and 2d echo to first to rule out heart diseases because this can cause similar symptoms.
If both of these are normal then no need to worry for heart diseases.
GERD is due laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the
esophagus and cause the symptoms of
chest pain, pressure, stomach pain etc.
So avoid
stress and tension, be relax and calm.
Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals.
Take
proton pump inhibitors and prokinetic drugs.
Quit
smoking and alcohol if you have these habits.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
