Why does my chest hurt after being hurt emotionally by people?

Muscle or heart pain. When you are emptionally hurt, you get sympathetic nerve increase which stimulates the brain to send increase signals to your muscles which can cause your pectoral muscles to have sustained contraction causing atypical chest pain. Norepinephrine surge can also cause coronary arteries to contrixt, decreasing blood flow to the heart which also can cause chest pain. I would go for a thallium stress.
