I got punched in the center of my chest super hard the other night, it hurt and hurt and hurt that night woke up the next day and it hurts if I stretch to far a way the obviously muscle that's lead to the Chest, it hurts if I do that, and if I sneeze, that's the worst. Cough, yawn it ain't horrid pain but it sucks to say the least. Just wanna make sure it ain't serious
