Thanks for your question on Healthcare Magic.
I can understand your concern.
Most common cause for these symptoms is stress and anxiety.
But better to rule out cardiac causes (
hypertension, arrhythmia) and
hyperthyroidism first.
So get done blood pressure monitoring, ecg, 2d echo,
stress test and Holter monitoring (24 hours continuous recording of Ecg).
If all these are normal then no need to worry for heart diseases.
Also get done thyroid function test to rule out hyperthyroidism.
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.
