Some people consider anything between their knees and the neck to be chest pain. Some people call a painful cough, or sore throat, or a stomach ache chest pain. I even had a guy complain of chest pain because he had sunburn. However, because the chest contains some of the most important vital organs, lungs and heart, it could be something serious. Ask him about his pain where it hurts and what brough it on, and what makes it come and go. If it is something like a mosquito bite that really itches that's one thing. But if in doubt play it safe, take him to the doctor.
