Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should first rule out cardiac cause for your symptoms because left sided
chest pain and shoulder discomfort are more associated with heart diseases.
So get done ecg, 2d echo and
stress test (trade mill test) first.
If all these are normal then no need to worry for heart diseases.
Sometimes, stress and
anxiety can also cause similar symptoms.
So avoid stress and tension, be relax and calm.
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 with all these. But first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
