Hi
Thanks for posting your query.
I need to know your age and since how long you are having these problems.
Few possible causes are :
1. Cervical radiculopathy:
Nerve compression at the level of back of spine can cause pain or
numbness or tightness in neck arm back chest region.
2. Heart problems: Inadequate blood supply to heart can cause the problems you are facing.
3.
Esophageal disease : Problems in food pipe like ulcer constriction of food pipe spasm of food pipe can cause your problems.
If i was your doctor i would have got an ECG and Echo test to make sure your heart is ok or not.If it comes normal then i advise you to get upper gastrointestinal
endoscopy to look in your oesophagus and lastly a MRI
cervical spine to see for nerve compression.
Kindly get the tests and revert back
Any clarification feel free to ask .
Regards.
