I feel some allergen is causing swollen airways(chest tightness).how to manage it with otc meds or other remedies, until i see my allergist?

Call your allergist: If you are having bothersome symptoms, just call the office - they will get you in right away, or tell you what you can do. If you already have a diagnosis of asthma, use your rescue inhaler. If you don't have one, hot, caffeinated beverages often have a mild effect to relieve chest tightness. But call your allergist - particularly if breathing problems are a new symptom for you,they'll get you in
