Welcome to HCM
We understand your concerns
You should not worry and be anxious too much. Pain the chest region alone cannot be a sign of heart attack
until it is accompanied with palpitation
, sweating, gasping for air etc,. also the pain may not continue for more than an hour. But you should visit a general practitioner to confirm this with the help of his experience and an EKG. Don't worry. Acidity and gastric problems do crate such pains.
Get well soon.
