Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of acute bronchitis is more. Acute bronchitis can cause bronchospasm and this can cause coughing a wheezing sound while coughing. So better to take him to doctor an get done clinical examination of respiratory system for the diagnosis of wheezing. He may need inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (budesonide or fluticasone). Don t worry, he will be alright. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
