Thanks for your question on Health Care Magic.
I can understand your concern.
Since your extensive cardiac work up is normal, possibility of GERD (
gastroesophageal reflux disease) related pain is more in your case.
GERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the
esophagus and cause the symptoms of burning, stabbing
chest pain.
So do following things for better symptomatic relief.
1. Avoid stress and tension.
2. Avoid hot and spicy food. Avoid junk food.
3. Avoid large meals, instead take frequent small meals.
4. Start
proton pump inhibitors and prokinetic drugs.
5. Go for walking after meals.
6. Quit
smoking and alcohol if you have these habits.
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.
