Allergies to substances in the environment are very common triggers. These may include pet dander, pollen, mold spores, and microscopic dust mites lurking in bedding and carpets.  When sensitive people inhale airborne irritants, they can experience a variety of irritating reactions. Symptoms typically involve nasal and respiratory complaints like repetitive sneezing, sniffles, postnasal drip and sinus congestion.  In severe cases, some undergo asthma attacks when seasonal allergens or other triggers inflame airway linings. Rather than managing endless symptoms with medications, we investigate root causes.
