General Information. Hives are red and sometimes itchy bumps on your skin. An allergic reaction to a drug or food usually causes them. Allergic reactions cause your body to release chemicals that can make your skin swell up in hives. People who have other allergies are more likely to get hives than other people. Other causes include infections and stress..  Dr. Liana Abramova and her staff specialize in the diagnosis of hives and will help you understand and manage the condition effectively.  Call Dermatology of Virginia in Fairfax at (703) 828-7128 and schedule your appointment today
