What Are the Causes of Hives & Inflammation?

Hives and inflammation are common skin conditions, according to the University of Maryland Medical Center (UMMC). Hives are itchy red welts that occur in batches; skin inflammation---also known as a rash or dermatitis---is a change the appearance and/or texture of your skin.
  1. Causes

    • The chemicals in latex, rubber, dish detergents, dye or cosmetics may cause hives and inflammation. Insect bites, food and medication can also trigger allergic reactions.

    Considerations

    • Serious illnesses also may cause hives or inflammation. Leukemia, hepatitis, and lupus can trigger hives; rheumatoid arthritis and Kawasaki disease cause inflammation of the skin, reports the National Institutes of Health (NIH).

    Diagnosis

    • To diagnose hives or skin inflammation, your doctor will ask about your medical history. The Mayo Clinic says skin prick tests, patch tests and intradermal tests---all of which apply allergens to your skin in different ways---along with blood tests, can help your doctor determine your allergy triggers.

    Treatment

    • Hives and inflammation may fade on their own. For severe cases, the UMMC says, antihistamines, epinephrine, or corticosteroids may reduce itching and swelling.

    Warning

    • See a doctor if you have joint pain, fever, swelling or tenderness, or a sore throat. Shortness of breath or problems swallowing indicate a serious allergic reaction---if you experience these symptoms, call 911.
