Hello. Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. Were I treating you, I would suggest you regular montelukast and levocetirizine for 2-3 months. I would also suggest you to use inhaler like salbutamol or levosalbutamol on as-and-when-needed basis for asthma symptoms/breathlessness/wheezing. 2. I would suggest you allergy testing, which will help you identify the substances causing symptoms to you and to know the measures to avoid them. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to improve allergy symptoms over long-term basis. 3. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution as much as possible. 4. Regular breathing exercises and a healthy diet will help you improve your lung capacity and immunity respectively over a long period gradually. 5. I would suggest to consult an Pulmonologist and an Allergist-Immunologist in New Delhi. I cannot violate T&Cs by suggesting you a particular doctor in Delhi, but some institutes like VP Chest Institute, AIIMS have very good doctors who can deal with your current problems. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you & Regards.
