Thanks forThanks for your question on Healthcare Magic. 
I can understand your concern. 
No, I don't think these symptoms are 
nerve related. 
By your history and description, possibility of 
stress and 
anxiety related symptoms is more. 
But better to rule out heart diseases first because left sided chest and arm discomfort are commonly seen with heart diseases. 
So get done ecg and 2d echo first. 
If both these are normal then no need to worry for heart diseases. 
Uncontrolled stress and anxiety can also cause similar 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.
