An itchy outbreak is a condition characterized by an uncomfortable sensation on the skin that causes a person to want to scratch. This condition can be caused by a variety of factors, including allergies, infections, and environmental irritants. Two common symptoms of an itchy outbreak are RASH and HIVES. A RASH is a skin condition characterized by redness, itching, and sometimes bumps or blisters. HIVES are raised, red, itchy welts that can appear anywhere on the body.
