Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should first rule out heart diseases for your symptoms because left sided
chest pain, breathlessness are common symptoms of heart diseases.
So get done ecg, 2d echo and
stress test (trade mill test).
If all these are normal then no need to worry for heart diseases.
Undiagnosed stress and
anxiety can also cause similar symptoms.
So better to
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on its solution.
You will also need anxiolytic drugs.
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.
