Hello. Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. First of all, I would like to know which nasal spray you used to have. If it is decongestant type of spray (xylometazoline), I would not suggest you to use it often. If it is an intranasal corticosteroid (fluticasone or mometasone), I would suggest you to use it daily at least for 2 weeks with proper technique. 2. At present, I would also suggest you to take daily montelukast and levocetirizine for at least 2-4 weeks. 3. As you already have had endoscopy recently by an ENT surgeon, it is easier for me to make suggestions to you. 4. As an Allergist-Immunologist, I would suggest you allergy testing for common air-borne allergy causing substances like - house dust mites, cockroach proteins, common molds & pollens in your area, animal dander (if you have pets), etc. Allergy testing will help you to identify substances causing allergies to you as well as to know how to avoid exposure to them. 5. Based on allergy testing, an Allergist-Immunologist may prescribe you specific allergen immunotherapy which works on your immune system to gradually improve allergy symptoms on long term basis. 6. In general, I would suggest you to avoid exposure to dusts, smokes and air pollution. 7. Regular breathing exercises and a healthy diet rich in vitamins & minerals will be helpful to you in a long run by improving your lung capacity and immunity respectively. In reply to your specific query (whom should you consult), I would like to suggest you that allergic rhinitis is best managed by a team consisting of an ENT specialist and an Allergist-Immunologist. ENT specialist takes care of symptoms and Allergist takes care of allergy itself and immune system. Hope above suggestions and information 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.
