Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
stress and
anxiety related
chest pain is more.
But better to first rule out heart related chest pain because left sided chest pain is commonly associated with heart diseases.
So first get done ecg and 2d echo.
If both these are normal then no need to worry for heart diseases.
In my opinion, you should
consult psychiatrist and get done
counselling sessions.
Try to identify stressor in your life and start working on it's.
You will need anxiolytic drugs too. Counselling along with these drugs will help you in sleep as well as stress reduction.
Apply warm water pad on affected areas. Avoid movements causing pain. Avoid bad postures in sleep. Avoid heavyweight lifting and strenuous exercise. Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
