Thank you for the input.
I am very sorry for your symptoms.
I understand your concern.
The pain in that part of chest can be due to a few causes.
Heart disease like ischemia is unlikely to cause it for less than a second.
It can be from muscle spasm, pinched nerve.
Nerve pinching can be felt in the back too.
It can come from reflux of acid too.
Anxiety or stress can be associated.
You can try Tylenol for the pain.
I hope this information will be helpful.
