Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, you should definitely concerned about this squeezing type of pain.
Possibility of cardiac chest pain (angina) is more because you already had MI (
myocardial ischemia).
So immediately
consult doctor and get done ecg, 2d echo and
stress test (trade mill test) to rule out heart diseases.
If all these reports are normal then GERD (
gastroesophageal reflux disease) can be the cause.
It 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 central squeezing type of pain.
So take
proton pump inhibitors and prokinetic drugs. Avoid hot and spicy food.
Don't worry, you will be alright, but first rule out cardiac chest pain.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
