my son 5 years ago, he starts coughing as soon as comes to home after playing. it's dry cough & whole day he doesn't cough. cough trigeers only in evening that too after coming from play at 7pm. what to do, why is it so

A. It could be just associated with getting tired and allergy that is very common with lots of kids but it is a sign of an allergy don’t take it I would recommend you to consult a doctor and get an allergy test done one time to start with the right treatment
