Hives Q & A

What are hives?

Hives (urticaria) are raised, red bumps or patches called wheals that suddenly appear on your skin. Individual hives can disappear within 24 hours, but new hives may continue to develop, creating a reaction that lasts several days. You have chronic hives when the wheals last longer than six weeks.


Hives have qualities that set them apart from other skin rashes:


  • Wheals appear and disappear quickly
  • Red hives turn white when you press on the area
  • Hives can change shapes


Hives can vary in size and may be oval, round, or worm-shaped. Individual hives can also merge into one large area.

What other symptoms develop when I have hives?

Hives are itchy, sometimes extremely itchy, and many patients also develop angioedema along with their hives. Angioedema develops as fluids accumulate in the tissues beneath your skin, making the area red, swollen, and painful.


Hives are uncomfortable, but they’re not dangerous. However, if they occur together with symptoms such as difficulty breathing, stomach cramps, or a swollen tongue or throat, hives could be part of a serious allergic reaction that requires immediate medical care.

What causes hives?

Hives are a common symptom of allergies to:


  • Food
  • Pollen
  • Poison ivy
  • Insect stings
  • Medications
  • Latex


However, hives are also caused by other problems such as:


  • Viral infections
  • Thyroid disease
  • Scratching your skin
  • Contact with chemicals
  • Chronic stress


You can even develop hives in response to sunlight and changes in temperature.

How do you treat hives?

Your provider at South Bay Allergy and Asthma Group examines your hives, reviews your medical history, and may run blood tests to rule out underlying infections or health conditions. 


If this is the first time you’ve had hives and your symptoms are mild, you may not need treatment other than medication to relieve the itch until the hives run their course.


If your provider suspects your hives are caused by allergies, they perform allergy testing in the office to determine which substances triggered the problem. The next step is to create a plan to avoid your triggers.


Hives are directly treated with medications, such as antihistamines and anti-inflammatory drugs. If these medications don’t relieve the itching and inflammation, your provider may talk with you about prescribing immunosuppressants.


Chronic hives that don’t have an identifiable cause, such as allergies, often fail to respond to antihistamines. If you face chronic hives, the team explores other options, which may include advanced biologics that help control your symptoms and prevent your hives from getting worse.
