Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. As you have long standing symptoms and severe symptoms, were I treating you, I would suggest you intranasal corticosteroid spray (mometasone or fluticasone) upon awakening in the morning for 14 days. I would also suggest you to take monteluakst and cetirizine for at least 2-3 months daily before going to bed. Both the above drugs will improve your symptoms significantly. 2. To identify the allergies, I would suggest you allergy testing, especially for common air-borne allergens like house dust mites, indoor molds, insect proteins and pet dander (if you have pet). This will help you identify the substances you may be allergic to and also to know the measures to avoid them. 3.Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve your allergy symptoms over a long period. 4. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution as much as possible. 5. Regular breathing exercises and a healthy diet rich in vitamins & minerals (plenty of green leafy vegetables, fresh fruits, sprouts, etc) will also help you in a long run by improving your lung capacity and immunity respectively. 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 ahead. Thank you & Regards.
