Answer 1

In this situation, patient has chest pain. Chest pain is a visceral pain that is mediated by the autonomic nervous system.

[ Notes: Pain stimulates the sympathetic nervous system, which in turn increases heart rate (HR) and causes peripheral vasoconstriction. severe pain from an injury or other stimulus, if continued over some period, was found to alter the neurochemistry of the central nervous system, thereby sensitizing it and giving rise to neuronal changes that endure after the initial stimulus is removed. That process is perceived as chronic pain by the affected individual. The involvement of neuronal changes in the central nervous system in the development of chronic pain].
