Thanks for using Healthcaremagic,
You have mild chest pain
and shivering your description of pain is unlikely related to heart.
This could be due to anxiety hence you must get examined and tested for ECG and other test including a stress test
to rule out any chance of cardiac origin.
Once everything is fine your physician can advise and give treatment for your problem.
Other differential could be acid peptic disorder and reflux disease, cervical spondylosis
or simple muscular pain
Please take care
