Thanks for your question on Healthcare Magic.
I can understand your concern.
Since you were a smoker and having left sided
chest pain, we should definitely rule out heart diseases first.
So get done ecg and 2d echo.
If both these are normal then no need to worry for heart diseases.
Sometimes undiagnosed stress and anxiety can also cause similar kind of dull left sided chest pain.
So
consult psychiatrist and get done
counselling sessions.
Try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs (
propranolol and
flunarizine combination) too.
Don't worry, you will be alright with all these.
Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
