Welcome to Healthcaremagic.
Concerning your age, it is unlikely that it would be a heart attack
. Heart attack symptoms typically occur after exertion and they last for a short period of time (about 3 minutes) and are relieved by rest.
Most probably this is due to GERD
. My Advices are:
- Leave 2 hours period between meals and lying down.
- Avoid eating chocolate, fatty foods, drinking citrus drinks.
- Elevate the head of your bed.
- If you are overweight
, try reducing your weight.
