My son is only a teenager, and his chest has been feeling pretty tight lately after he does physical activity. What could be causing this?
While heart disease is rare in teenagers, there are well known congenital abnormalities - problems that people are born with - that can first cause symptoms in teenage years and avoid detection by pediatricians when the individual is younger. He should be evaluated by a cardiologist if his chest tightness continues.
Most likely lungs are the problem. Exercise induced asthma maybe. An echo and ecg should be done. Maybe a holter as well
He could have exercise induced asthma. He could have reflux or allergies can cause this. He would need to be checked
