The Truth About Chronic Hives: When a Rash Isn’t Just a Rash

Anyone can get hives, and in many causes, the rash goes away quickly without treatment. But what if hives don’t go away?

If you have a red, itchy rash that lasts more than six weeks, even if it comes and goes, you have chronic hives. While the exact cause of the rash isn’t always known, you can get relief with the right treatment.

At Associated Skin Care Specialists, our board-certified dermatologists are experts in diagnosing and treating skin disorders like chronic hives. We offer the latest treatments to help you manage symptoms and improve your quality of life.

While most rashes are harmless, not all rashes are the same. Here, we share what you need to know about chronic hives and how we can help.

About hives

Hives, or urticaria, are raised red or skin-colored bumps or patches on the skin that usually cause intense itching. The rash occurs when your immune cells release histamine, causing blood vessels to expand and leak fluid, leading to the bumps. Histamine also irritates the sensory nerves, triggering the itchy sensation.

Hives come on fast and may disappear within a day, but they also can last a few days or a few weeks. It’s also not unusual for the rash to disappear in one area and reappear elsewhere.

Though very uncomfortable, hives are generally harmless. However, you should seek urgent care if your hives make it hard to swallow or breathe or cause lightheadedness. These symptoms are signs of a serious allergic reaction and need immediate medical care.

While hives have no cure, taking steps to relieve the itching is important to avoid skin damage and reduce the risk of infection. Simple remedies like cold compresses or over-the-counter (OTC) anti-itch creams can soothe the discomfort.

When hives turn chronic

Hives can last several weeks, but when they stick around for more than six weeks, we consider the condition chronic. For some people, hives may persist for several months. 

If your hives last longer than six weeks, it’s time to schedule an appointment with one of our skilled dermatologists. We can try to identify the cause of your rash and create a personalized plan that helps you get relief from your symptoms. 

Causes of chronic hives

Experts say that 80 to 90% of people with chronic hives don’t know the cause. In some cases, the rash is caused by an underlying autoimmune disorder, such as lupus or rheumatoid arthritis.

Other possible triggers include:

• Rapid changes in body temperature
• Stress
• Infections
• Medications 

Despite what you might think, allergies rarely cause chronic hives. Fortunately, even when the cause is unclear, we can provide effective treatments. 

Getting relief from the itch

Antihistamines are the primary treatment for chronic hives. However, the right medication and dose can vary from person to person.  

We may also recommend a topical anti-itch or corticosteroid cream if your case is mild. If your hives are severe, you may benefit from a short course of oral corticosteroids. 

If antihistamines can’t fully control your flare-ups, we may prescribe medications that block the production of histamine or other chemicals involved in the allergic or inflammatory process.

Don’t ignore a rash that lingers. Chronic hives can interfere with your sleep, work, and overall quality of life. We can help you get relief and feel comfortable in your skin.
