Hello and welcome to HCM
As per your mail it does't seems that it is a heart pain because you don't have shortness of breath
but to sure some more detail history is needed?
But I can tell you symptoms of Heart pain:
Pain in chest (almost whole chest) with shortness of breath, Ghabharat, Palpitation
and discomfort, Pain radiating to shoulder and arm. If these symptoms present than you can say it is a heart pain and you needs investigation. If you can pin point the site of pain than it never be a heart pain.
So leave your anxiety
and if you have any doubt than get investigation and rule out it by consulting your doctor.
