i don't think so, i am a physician, heart attack
involves left side of the body: left arm and the left side of the chin. i think your problem relates to your digestive system, may be overeating or eating a heavy and hard to digest meal. don't worry. but it is better to wake your father up and tell him about it calmly.
you can try drinking some mint water, or chamomile water also. don't worry dear friend.
