If your eyes itch and are red, tearing or burning, you may have eye allergies (allergic conjunctivitis), a condition that affects millions of Americans. Many people will treat their nasal allergy symptoms but ignore their itchy, red, watery eyes.
Dust allergies also make it difficult to breathe and may trigger asthma symptoms, such as wheezing, coughing, tightness in the chest and shortness of breath. Visit Mission Allergy for more information.
Bumps, itching, redness and other skin conditions are very common, and their cause may not be easily identifiable. Eczema and hives, both of which are related to allergies, are two of the most common skin rashes.
Mold allergies can be tough to outrun. The fungus can grow in your basement, in your bathroom, in the cabinet under your sink where a leak went undetected, in the pile of dead leaves in your backyard and in the field of uncut grass down the road.
If you sneeze a lot, if your nose is often runny or stuffy, or if your eyes, mouth or skin often feels itchy, you may have allergic rhinitis, a condition that affects 40 million to 60 million Americans.
