We know cardiac pain is often referred to Jaw and neck .
What prevents the neck pain of cervical spinal disease to be referred over the heart ? Can pure spinal lesions mimic angina ?
The answer seems to be “Yes” . The neuronal circuit is there .Only , the traffic has to be reversed. Medical logic is always puzzling. There is indeed an entity called cervical angina.
The cardiac pain can be referred any where between dermatomes C3 to T 10 It is generally believed cervical radicular pain can go only one way . . . ie towards the nape of neck and arms .Dermatomal overlap ,neural cross talks thalamic inputs and cortical reflection and perception always make the subject of referred pain too complex.
Now,It seems possible ,the neck pain can spill over into the anterior chest wall ,mimicking angina .Imagine the confusion if the patient has both cardiac and cervical entities ! Does the pain signals from the two sites collide in the local spinal network ? Does one extinguish or amplify the other ?

Dear Dr. Venkatesn,
You blog is really interesting and informative even for heart patients like me.
I would really appreciate if you could give me some advice.
I am 59 years old and had CABG in LAD artery 5 years ago.I am under cardiologist prescribed medication for BP, nitroglycerin, statin and anti-clotting. I am having chest pain with the focus in the sternum region. My activity level has also gone down due to chest pain. Occasionally, when my BP increases to above 150/100 I also get clear left-side chest pain and left-arm pain. My cardiologist has advised that further surgery will not help and medication is the only way out. Would like your assessment regarding how I can improve my heart condition and reduce the chest pain. I have gone through some weight loss and do about 30 minutes of walking every day.
Regards,
