An allergy is an abnormal reaction or increased sensitivity to certain substances. The allergic individual produces symptoms when exposed to these substances which are harmless to non-allergic people. House dust mites, furry pets, molds and fungi and cockroaches are some indoor allergens.
Pollens including trees, grasses, weeds and ragweed are some outdoor allergens.
Allergy sufferers experience a swollen nose lining that exudes a runny discharge. Spells of sneezing and itchiness of the throat and palate also occur and the eyes may be similarly affected. Contact your physician for a thorough evaluation.
