Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of stress and
anxiety related symptoms is more.
But better to rule out
hypertension and heart diseases because headache and
chest pain are common symptoms of these diseases.
So get done ecg and 2d echo.
If both are normal then no need to worry for heart diseases.
Uncontrolled stress and anxiety can also cause similar symptoms.
So
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on it's solution.
You may need anxiolytic drugs too.
Don't worry, you will be alright. 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.
