What are some of the symptoms of allergies?

Allergy Symptoms: Allergic rhinitis symptoms include sneezing, runny nose, nasal congestion, itchy nose or eyes, sinus pressure, tearing, red eyes, ear fullness, post-nasal drainage. Allergic symptoms in the skin or lungs can manifest differently but usually when one asks about "allergy" symptoms it most commonly refers to rhinitis.

LONG list: Allergies come in many forms. Most people think of allergies as causing nose and sinus problems such as sneezing, nasal drainage, and congestion, however, other symptoms can include itchy and watery eyes, or in more severe cases, rash, nausea, vomiting, difficulty breathing, and even confusion or dizziness.
