Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, you should definitely visit to the hospital and rule heart related diseases because your symptoms are commonly seen with heart diseases.
So get done ecg, 2d echo and
stress test.
If all these are normal then no need to worry for heart diseases.
You are also having sleep disturbances, so this can cause stress and
anxiety and they then cause all the 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.
