My asthma is flaring up. does it have to with high pollen level?

Possibly: A variety of triggers can cause your asthma to flare. Pollen allergy is certainly one potential trigger, as are other allergens such as pets, dust mites, and molds; colds and other viruses, bacterial infections such as sinusitis, poor air quality, acid reflux, and multiple other triggers. See your doctor to treat your asthma and help determine your triggers.
