Hello and thank you for using HCM.
I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that chest pains might have different reasons like cardiac, skeletic, muscular or gastrointestinal.
Usaly cardiac chest pains have some characteristics. They usually are retro-sternal pains like squizzing , tightness or heaviness.
They irradiate to both arms , neck and jaw and last from 5-20 minutes.But this heart pains and problems are manifested in older ages, not in very young age like yours.
Another reason might be a muscular issue.This are pains that last long, are effected by different movements ect.
Another reason in younger ages might be just
stress or neurotic pains that come and go.
So, if I was your treating doctor I will recommend a cardiac echo to evaluate heart function and walls, a thorax rx and a fool blood analyze.
If this result normal than you should not worry.
Hope I was helpfull.
Best regards, Dr.Ervina.
