Years ago, I saw a TV medical show in which a doctor asked a patient to raise his arms over his head and report on whether his chest pain got better or worse. I've noticed that sometimes I have sharp pains in my chest, on one side or the other, particularly after I've carried suitcases. The pain often gets worse when I raise my arms. Does that indicate a heart condition or just muscle strain?
