Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. I usually suggest my such patients skin prick testing for molds, house dust mites, animal dander, pollens and insect proteins. Based on allergy testing, an Allergist-Immunologist may prescribe you allergen specific immunotherapy which works on immune system to gradually improve allergy symptoms over long period for long term basis. 2. For symptom control, I usually prescribe my patients regular Montelukast + Levocetirizine. 3. Dark circles under eyes usually occur due to long standing allergic rhinitis. With treatment of allergic rhinitis, they may improve or may not improve, especially if they are since long duration. 4. If you have nose obstruction despite use of above mentioned drugs, I would suggest you intranasal corticosteroids for a few days, which may help. 5. Regular steam inhalation will also help you in a long run. 6. In general, please avoid exposure to dusts, smokes, cold air and air pollution as much as possible. 7. Regular breathing exercises and a diet rich in vitamins & minerals will also help you in a long run by improving your nose symptoms 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.
