Hives

Hives are a frequent reaction, often caused by allergens or irritants.

While generally harmless, they can affect anyone, with approximately 20% of people experiencing them at some point in their lives.  Hives occur more frequently in women than in men and can be triggered by a variety of substances or medical conditions. They typically start as an itchy area of skin and progress into red, swollen welts or wheals that vary in shape and size.
