Seasonal?: Sounds like you may have allergic rhinitis to outdoor seasonal allergens like pollens of trees or grasses. If so, immunotherapy, antihistamines, and medications like singulair (montelukast) may help prevent attacks. Allergen-proofing your home using HEPA filters, changing air conditioning and heating filters, dustmite proof coverings of mattresses and boxsprings and pillows, and frequent cleaning may also help.

Likely: It is likely it will be an ongoing problem unless you move from the allergens. Consider a visit to the allergist and desensitization shots. You are doing the right thing by treating your allergies during allergy season. All the best.

Well, ...: It is tough to say. Seasonal allergies and Mild Reactive Airway Disease are very common. Some people do grow out of their seasonal issues, others need the months of medications. No guarantees with this one. Good luck.

Allergic asthma: If your asthma is caused by allergies, you should have allergy testing and get allergy shots (immunotherapy) to become desensitized to the allergens. If you know specifically what you are allergic to, remove them from your environment. Dust, mold, pet dander, plants are common allergens. Remain indoors during the day when the pollen is highest.
