What it means

Hives are red and sometimes itchy bumps on the skin; the MedlinePlus encyclopedia describes them as raised, usually itchy, red bumps (welts) on the surface of the skin. An allergic reaction to a drug or food usually causes them, and other causes include infections and stress. Allergic reactions cause the body to release chemicals that can make the skin swell up in hives. Hives are very common and usually go away on their own. Angioedema is swelling of the deeper tissue that sometimes occurs with hives. In rare cases, hives can cause a dangerous swelling in the airways that makes it hard to breathe, which is a medical emergency; emergency signs need urgent care (call 911 in the U.S.). In Spanish the term is urticaria.

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
