What are the symptoms of allergies?

Dr. Jeanne Morrison, PhD
Family Practitioner

Allergy symptoms can vary depending on the type of allergic reaction occurring. In general, allergy symptoms include watery or itchy eyes, a runny nose, itchy skin and sneezing. Rashes, hives and swelling may also be common. In anaphylactic reactions, more serious symptoms occur and can be deadly.
