Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, you should definitely
consult doctor as soon as possible to rule out
hypertension and other heart diseases.
You are having risk factors like stressful life,
smoking, alcohol ingestion and your symptoms are also favoring heart diseases.
So get done blood pressure monitoring, ecg, 2d echo and Holter monitoring (24 hour continuous monitoring of ecg).
If all these these are normal then no need to worry for hypertension and heart diseases.
Sometimes only stress can cause similar symptoms.
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.
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.
