Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, your son is mostly having allergic rhinitis and asthma. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test). PFT will not only diagnose asthma but it will also tell you about severity of the disease and treatment is based on severity only. He will definitely improve with inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Intranasal spray containing steroid (fluticasone) should also started in his case. Oral combination of antihistamine (levocetrizine or fexofenadine) and anti allergic (montelukast) is also beneficial. Don t worry, he will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
