So back to your question: 1  Your chest hurts when you're emotionally sad because your brain processes physical and social pain in the same brain regions (dACC and AI) (the affective aspects of the pain). The fact that both pains overlap means the factors that decrease physical pain also decrease emotional pain.
The following are clues that your chest pain is probably not caused by a heart problem: 1  You have pinpointed pain (you can point to the exact spot that hurts). 2  The pain gets worse when you take a deep breath; or, not breathing for a few seconds reduces the pain significantly.
