I Am Constantly Being Bombarded With Difficulty In Breathing. Especially

I am constantly being bombarded with difficulty in breathing. Especially through my nostrils. When this happens I also have trouble breathing through my throat, and be gin to wheeze. this has been happening now for a little over a month, and I contributed it to allergies, with all the pollen etc., but I have never before experienced this before now. I only feel the difficulty with breathing. I have no other symptoms.
