Hello...for your symptoms mainly 2 problems have to be ruled out.
1 is heart disease which can reliably be ruled out with a 2D ECHO first & then TMT/Stress test even if ECG is normal.
Secondly get a XRAY-CERVICAL SPINE (AP & lateral view) to rule out cervical spondylitis which may present with above symptoms & neuropathy.
Next Steps
With above reports u can revert back to me or consult a M.D physician/cardiologist.
