Hello. Thank you for asking at HCM. I went through your history. I would first think of allergic rhinitis from your history. I would like to make following suggestions to you: 1. Were I treating you, I would prescribe you montelukast and an anti-histamine like levocetirizine/cetirizine/fexofenadine for at least 2-4 weeks (depending upon response). 2. If your symptoms are very severe or they do not improve with above treatment, I would suggest you intranasal corticosteroid spray for at least 7-14 days (depending upon response). 3. Along with these medications, I would suggest you nasal irrigation with nasal saline drops at least 3-4 times a day as well as daily washing your eyes with clean water 3-4 times day. This will help to reduce your medication requirement. 4. Please try to avoid exposure to dusts, smokes, cold air currents and air pollution as much as possible. You can cover your nostrils with cloth/handkerchief/mask in case of possible exposure to these irritants. 5. From the pattern of your symptoms (more in morning, upon opening of windows) I would first think of allergy to house dust mite or pollens. To confirm the diagnosis, I would suggest you allergy skin/serum testing which will help you to identify the substances you are allergic to and also to know measures to avoid them. 6. I would also suggest you to consult an Allergist-Immunologist who can advise you specific allergen immunotherapy based on results of your allergy testing, which will work on your immune system to improve your allergy symptoms gradually. 7. A healthy diet rich in vitamins, minerals and anti-oxidants (e.g., green leafy vegetables, fruits, sprouts, etc) will help you in a longer run. Hope above measures will be helpful to you. Wish you the best of the health. Should you have any further query, please feel free to ask at HCM. Thank you & Regards.
