Corticosteroids: You may benefit from addition of corticosteroids to your treatment.

Allergy asthma meds: It sounds like you have severe allergies and some asthma . OTC sprays Nasacort and Flonase help nasal symptoms but take a few days to kick in . Singulair (montelukast) is a prescription pill that can help with nasal or chest symptoms . Steroid inhalers are important for asthma (e.g. Qvar, Flovent). If allergies are severe, see an allergist and get skin tests. Allergy shots are better than meds for long term.
