Thanks for your question on Healthcare Magic.
I can understand your concern.
Your
chest pain is on left sided, sharp in nature and associated with emotion (crying).
All these are seen with either heart diseases or
stress and
anxiety.
So better to first rule out heart diseases.
So get done ecg and 2d echo.
If both are normal then no need to worry much.
Stress and anxiety are more likely in your case because you are in your teenage.
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.
