Thanks for your question on Health Care Magic.
I can understand your concern.
Better to first rule out cardiac diseases for your
chest pain because left sided chest pain, left
arm pain are common in heart diseases.
So get done ecg and 2d echo.
If both are normal than no need to worry for heart diseases.
Sometimes,
stress and
anxiety can also cause similar symptoms.
So better to avoid stress and tension.
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.
Hope I have solved your query.
Wish you good health. Thanks.
