What Causes Hives? Chronic Symptoms, Triggers, and When to Seek Care

Hives—also known as urticaria—are itchy, red, and sometimes swollen bumps on the skin that may appear suddenly and disappear within hours or days. When hives persist for more than six weeks or recur frequently, they are considered chronic hives.

Though often not dangerous, chronic hives can significantly affect your quality of life. Here’s everything you need to know about symptoms, triggers, and treatment options.

Are Hives the Same as a Rash?

Not exactly. A rash is a general term for skin irritation or inflammation and can appear in many forms, while hives are a specific type of rash characterized by raised, red welts that often itch and move around the body. If your “rash” seems to come and go, or appears in response to environmental triggers, it may actually be chronic hives.

Common Triggers for Chronic Hives

While the exact cause of chronic hives is often unknown, common triggers include:

• Foods (especially nuts, shellfish, or eggs)
• Temperature extremes
• Stress or anxiety
• Medications (NSAIDs, antibiotics)
• Infections or illnesses
• Pressure on the skin from tight clothing

Keeping a symptom diary may help identify your personal triggers.

Signs You May Have Chronic Hives

• Itchy red welts or bumps that last for more than six weeks
• Welts that fade in one area and reappear elsewhere
• Swelling of the lips, eyelids, hands, or feet (angioedema)
• Hives triggered by heat, cold, exercise, or stress
• Frequent flare-ups that disrupt your daily life

If any of these sound familiar, it’s time to speak with your primary care provider (PCP).

Home Remedies for Chronic Hives

1. Wear Loose, Breathable Clothing

Tight clothing can worsen irritation. Choose cotton or soft, breathable fabrics to reduce skin friction.

2. Apply Cool Compresses

Cold helps calm inflammation and itchiness. Avoid heat, which can trigger flare-ups.

3. Take Antihistamines

Over-the-counter medications like loratadine or cetirizine can help reduce itching and swelling.

4. Avoid Known Triggers

Log your diet, environment, or emotional state before flare-ups. This may help you pinpoint a trigger.

5. Minimize Stress

Stress is a known trigger for many people. Try relaxation techniques like yoga, meditation, or journaling.

When to See a Doctor for Chronic Hives

While hives often resolve on their own, you should contact your doctor if:

• Hives are persistent or getting worse
• They interfere with sleep or daily activities
• You experience swelling of the throat or lips (seek emergency care)
• Over-the-counter medications don’t provide relief

At BASS Medical Group, our primary care providers can evaluate your symptoms, rule out serious causes, and prescribe medications to help manage your hives. If needed, we can refer you to a trusted dermatologist or allergist for further care.

Can Chronic Hives Be a Sign of Something More Serious?

In rare cases, chronic hives may be linked to autoimmune conditions or chronic infections. That’s why it’s important to consult a provider if you experience ongoing or worsening symptoms. Your PCP can order bloodwork or additional tests to rule out underlying health issues.
