Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Since your ecg and blood report are normal, no need to worry for heart diseases.
Also get done chest
x ray to rule out lung pathology because this can also cause similar kind of
chest pain. If chest x ray is normal than no need to worry much.
Sometimes
stress and
anxiety can cause similar kind of pain.
So better to
consult psychiatrist and get done counseling 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.
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.
