Thanks for your question on Health Care Magic.
I can understand your concern.
Honestly speaking, it is very difficult to differentiate between gas pain and heart pain.
But heart pain is more severe kind of pain as compare to gas pain.
It is basically excruciating type of pain with perspiration, sweating, chest heaviness.
Heart pain is also radiating to left jaw, left shoulder and arm.
But these classical differences may not seen all the time. Many times, heart patients are complaining of gas pain and it is actually found out to be of heart pain.
So better to get done heart work up like ecg, 2d echo and
stress test to rule out heart pain.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
