Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should first rule out heart diseases for your
chest tightness.
So get done blood pressure monitoring, ecg, 2d echo and
stress test (trade mill test).
If all these are normal then no need to worry for heart diseases.
Sometimes undiagnosed stress and
anxiety can also cause chest tightness.
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 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.
