My Teen Son Has A Cold. He Is Not Running

My teen son has a cold. He is not running a fever, but is complaining his lungs feel like they are on fire. He is an athlete who will be wrestling in a very competitive high school tournament this Saturday. Is this a common symptom of a cold or should I take him in to be evaluated by a doctor? I don't want to ignore his condition if the chances are it could be more serious than a cold.
