My 6yo has had a cold for the last several weeks - cough, congestion, sneezing...yellow mucous.  Today, he barely drank any water while at school, came home and took a nap (not typical for him), and says that it hurts to breathe.  Im concerned as asthma runs in the family.
Hi, These symptoms can be due to asthma but more suggestive of acute viral infection turning to bacterial. So no need to worry about single episode of infection. Treat it with antibiotic and other supportive medications (based on examination). Also get tested for bronchi dilators challenge test and spirometry. These will help in diagnosing asthma. Hope this information helps you. Feel free to ask if any further queries and I will be glad to answer them. Regards
