Hi , Allergic rhinitis is an allergic response to specific allergens. Pollen is the most common allergen in seasonal allergic rhinitis. These are allergy symptoms that occur with the change of seasons You can go for allergen testing , like skin prick test

Allergic rhinitis is a defense mechanism of the body to prevent the entry of substances which it recognizes as foreign. The only way to reduce allergies is not with medication but with avoidance of the offending allergen. Please observe the things which lead to increase in your symptoms and try to avoid them.. Taking steam at night may help in reducing the amount of exposure of allergen to the nose
