Hives, also known as urticaria, affects about 20 percent of people at some time during their lives. It can be triggered by many substances or situations, and usually starts as an itchy patch of skin that turns into swollen red welts. The itching may be mild to severe. Scratching, alcoholic beverages, exercise and emotional stress may worsen the itching.

Hives Symptoms

  • Raised itchy bumps, either red or skin-colored
  • “Blanching” (when pressed, the center of a red hive turns white)
