Thanks for the query
Your age is not that for heart problems but as you said you smoke too although not that much plus use alcohal also and also going through stress
. so all these factors can contribute to heart problem
Actually the symptom like chest pain
is always take much serious especially left side due to presence of heart in the region. Therefore, it is always take as emergency and never ignored as some other conditions like anxiety
do cause such symptoms but the priority is always give to rule out cardiac conditions first.
Therefore, it is recommended to visit ER and have an ECG to rule out any heart problems
