I agree that it's important to know what is causing the symptoms.  I used to believe that I was experiencing heart attacks and actually ended up in the ER a couple of times (by ambulance) only to learn that I was experiencing panic attacks.  Because the symptoms were synonymous with cardiac arrest, I always went to the ER.  Now, I know the symptoms of the panic disorder.

Chest pains can result from any number of conditions, and without knowing what is causing them, it's impossible to develop a natural protocol to treat the condition, instead of the symptoms.

Get a complete physical and the lab work to determine what may (or, may not) be causing the symptoms.  Then, you can treat the condition via natural / alternative methods.

Best wishes to you.
