Hello, Thank you for asking at Chat Doctor. 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, pollen 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 Chat Doctor. 5.
