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 first get done ecg to rule out heart diseases.
If ecg is normal then no need to worry for cardiac diseases.
You are also taking
beta blocker. And this is mostly given to you for anxiety.
But only drug is not sufficient for anxiety management. Better to
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on it's solution.
Counselling plays very important part along with drug to control stress and anxiety.
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.
