Hives (Urticaria)

A relatively common allergic reaction, hives are red, swollen bumps that suddenly appear and can result in mild to severe itching, or even burning or stinging sensations. The size, location on the body, and duration of a hives outbreak vary widely.

Symptoms

Hives typically present with clearly defined borders and may blanch (turn white) in the center when pressed. If a large area of the body breaks out in hives, they may join together to form “plaques.” The itchy bumps may come and go, even moving around to different body parts.

Hives can appear in the blink of an eye and then disappear within minutes to hours. In rare instances, they last for weeks or even months.

Causes

A vast array of triggers cause allergic reactions resulting in hives. These triggers include:

Some people develop non-allergenic hives due to stress, heat, exercise, exposure to sunlight, infections, or autoimmune disorders. Even with all of the known causes of hives, sometimes a specific cause or trigger cannot be pinpointed.

Diagnosis & Treatment Options

Many hives outbreaks resolve on their own and do not require medical evaluation. If they persist over time, seem unusual, are accompanied by facial or airway swelling (angioedema), or interfere with daily life, please request an appointment with Harker Heights Allergy so we can evaluate your individual situation and work with you to discover what may be triggering your hives.

We will discuss your medical history and determine allergens present where you live and work. Further diagnostic options include skin and blood tests, which can help identify the culprit, as well as rule out many common triggers.

Let our allergy specialists work with you to identify medication that can ease symptoms or even eliminate hives while we complete your testing. Once identified, avoidance of your personal trigger(s) can end your battle with hives.
