My 5 year old son has displayed absolutely NO other symptoms (no runny nose, no cold, no fever, no loss of appetite, no loss of sleep, no sneezing
, no "allergy mask", no previous allergies to anything -- food or airborne, no symptoms of allergies.
He simply woke up
with a heavy cough. He doesn't have tightness in his chest, has not complained of shortness of breath (as he plays 1 hour of basketball), sleeps fine, etc.
