My son age 5 suffers I think of asthma since a very early age. I would like my doctor to refer me to see a paediatrician since over the past 3-4 months even a mild wet nose (early onset of a cold) will trigger the cough, and when there is an abrupt change of weather from cold/hot/windy. I would like him to have a blood test to determine whether he is allergy prone. Though my doctor says he is too young? is this the case? I would also like to know how bad it is. He is now on 3 different puffers brown, blue, and green, he has had coughs a week on and off over the past 3 months.
