Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Since you are having strong family history of heart diseases, better to first rule out cardiac cause for your
chest pain.
So get done blood pressure monitoring, ecg and 2d echo.
If all are normal than no need to worry for heart diseases.
Sometimes
stress and
anxiety can also cause similar kind of pain.
So if you are having stress and tension than avoid them, be relax and calm.
Don't worry, you will be alright.
But first rule out heart related diseases.
Hope I have solved your query.
Wish you good health. Thanks.
