Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of cough variant asthma is more likely. You are having family history of allergy. You are allergic to dust. Both of these are in favor of asthma more. 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. You will mostly improve with inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Continue montair LC, once a day at night. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
