What nerve is responsible for chest pain?
In the case of cardiac pain it seems that afferent sympathetic nerve activity, principally activated by adenosine, as discussed above, is responsible for the bulk of pain signalling from the heart to the spinal cord and brain. The vagus nerve appears to have a minor role in afferent pain transmission.
What causes pain in the left side of the chest?

Why does heart pain radiate to the left arm?

What is the sympathetic nerve to the heart?
Sympathetic nerves are responsible for: increasing heart rate. increasing the force of contraction of the myocardium. the ‘fight or flight’ response, causing our heart to beat faster.

Does magnesium help with lactic acid?
In good news, magnesium helps neutralize lactic acid. “Magnesium allows the body to burn fuel and create energy in an efficient cycle during exercise that does not lead to lactic acid production and buildup,” (The Magnesium Miracle, Kindle version page 2115).
Which of the following is associated with angina pectoris?
Angina pectoris occurs when your heart muscle (myocardium) does not get enough blood and oxygen. Not enough blood supply is called ischemia. Angina can be a symptom of coronary artery disease (CAD). This is when arteries that carry blood to your heart become narrowed and blocked.
