by Hives, also known as urticaria, are a common skin condition characterized by raised, itchy, red welts that can appear anywhere on the body. While hives may seem straightforward to identify on light skin, they can often look very different on darker skin tones. As a result, hives are frequently misdiagnosed in Black patients and patients of color.
In this comprehensive guide, we will cover everything you need to know about recognizing, treating, and preventing hives on darker skin.
Hives on Black Skin
What Are Hives?
Hives occur when the skin reacts to an irritant, allergen, or trigger, releasing histamine and other chemicals that cause fluid to accumulate under the surface of the skin. This results in distinctive raised welts or bumps.
The welts can range in size from a few millimeters to over 20 centimeters wide. They may first appear as small reddish spots that come together to form larger welts. The welts can change size and shape over hours.
While hives are often itchy, some patients report them feeling painful or burning. Hives typically last for a few hours before fading, but new hives may continue to appear for days to weeks.
Common Symptoms of Hives
- Welts, bumps, or raised areas on the skin
- Itching or burning sensations
- Tenderness to the touch
- Occurring in isolated groups or covering large areas
- Changing shape and size over hours
- Lasting for minutes to days before fading
Hives can occur anywhere on the body including the face, lips, tongue, throat, and ears. When they appear inside the mouth or throat, it is called angioedema. Hives combined with angioedema can be dangerous if swelling blocks the airways.
What Triggers Hives on Darker Skin People?
Hives are frequently triggered by an environmental exposure or allergic reaction. Common triggers include:
- Foods like shellfish, nuts, eggs, and fruits
- Medications like antibiotics, NSAIDs, and opioid painkillers
- Insect stings and bites
- Latex or other contact allergens
- Extreme temperatures
- Sun exposure
- Infection
- Stress
- Exercise
- Pet dander
- Pollen
- Plants like nettles
In around 50% of chronic hives cases, no exact trigger can be identified. These are classified as chronic spontaneous urticaria.
Why Hives Look Different on Darker Skin?
When hives occur on lighter skin, they often appear as raised red or pink welts. However, hives look very different on darker brown and black skin tones.
On darker skin, hives can appear lighter or darker than the surrounding skin. The color contrast may be quite subtle, making them harder to notice.
While hives on pale skin are starkly red and inflamed, hives on dark skin may not appear irritated even when they are itchy and painful. Their pigmentation can vary extensively based on an individual’s skin tone.
This poses a problem, as many medical students are not trained on the appearance of inflammatory skin conditions like hives on darker skin. As a result, hives are frequently misdiagnosed or overlooked in Black patients.
Recognizing Hives on Darker Skin Tones
To identify hives on darker skin, look for raised, often rounded welts that may be slightly lighter or darker than the surrounding skin. The welts change shape and size over time.
Even without significant color contrast, the texture of the skin changes with hives. Areas with hives look bumpy and swollen. They may also appear shiny or fluid-filled.
Here are some tips for identifying hives on darker skin tones:
- Look for texture changes – the welts appear raised or swollen
- Watch out for color variation – the welts may be slightly lighter or darker
- Check for shininess – hives can appear glossy or fluid-filled
- Feel for tenderness – gently touch the area to check for pain and swelling
- Consider the borders – the welts may have indistinct borders that change over time
- Monitor changes – observe the area over several hours for increasing welts
- Ask about itching – itching is common, even if welts are not readily visible
Some hives may be more subtle in appearance. However symptoms of pain, itching, and changeability over time help distinguish hives from other benign skin lesions on darker tones.
Types of Hives
Several categories of hives produce somewhat distinct symptoms:
- Acute Hives
Acute hives occur suddenly and last less than 6 weeks. Triggers include food, medications, insect bites, infections, and stress. Acute hives usually respond promptly to treatment but may return with re-exposure to the trigger.
- Chronic Hives
Chronic hives last over 6 weeks and often have no identifiable cause. The hives may stop for some time and then return. Antihistamines and immune-modulating drugs may be needed to control flare-ups.
- Physical Hives
Physical hives are triggered by stimuli like heat, cold, sunlight, pressure, exercise, and sweating. Swelling is often localized to the area of contact with the trigger. They typically resolve within an hour after the trigger is removed.
- Dermatographia
Dermatographia causes hives to form along “scratch lines” on the skin within minutes of light scratching or friction. These linear hives may last up to 30 minutes.
- Contact Hives
Contact hives occur on the skin directly exposed to an allergen or irritant. Examples include hives from latex gloves or poison ivy rash. They are often confined to the site of contact.
Diagnosing Hives in Darker Skin Tones
Unfortunately, many doctors receive little training in recognizing conditions like hives on darker skin. As a result, Black patients are often misdiagnosed.
Be your advocate by finding a dermatologist experienced in treating darker skin tones. If possible, get referrals from other patients with positive experiences.
To diagnose hives, your doctor should:
- Ask about symptoms like itching, pain, and timing of outbreaks
- Look closely for subtle signs like raised welts, texture changes, and mild pigment variations
- Consider typical triggers and exposures to identify likely causes
- Rule out skin infections that may have similar appearances
- Use aWood’s lamp to help identify inflammation invisible to the naked eye
If your doctor seems unsure about distinguishing hives from other conditions, don’t hesitate to get a second opinion from a more experienced dermatologist.
Treatments for Hives
The best treatment depends on the severity and type of hives:
Mild Acute Hives
- Over-the-counter antihistamines like Zyrtec or Claritin help relieve itching and swelling
- Cool compresses can help soothe itchy hives
- Avoid triggers like irritating foods while hives heal
If OTC meds don’t help within 1-2 days, see your doctor for prescription treatment options.
Severe Acute Hives
- Prescription antihistamines like hydroxyzine provide stronger, longer-lasting relief
- Short-course oral steroids rapidly reduce widespread hives
- Injectable epinephrine may be prescribed for emergency allergy attacks
Prolonged courses of steroids are not recommended for long-term hive treatment due to side effects.
Chronic Hives
- Daily high-dose antihistamines are the first-line treatment
- Alternative antihistamines may be tried if the first option is not effective
- Leukotriene inhibitors like montelukast help reduce inflammation
- Immunosuppressants can prevent recurrent hives if other treatments fail
Identifying and avoiding triggers is also important for minimizing chronic hive flare-ups.
Preventing Hives
While acute hives cannot always be prevented, the following measures can help reduce outbreaks:
- Avoid known triggers – Don’t eat foods, take medications, or use products that previously caused hives
- Treat infections promptly – Bacterial and viral illnesses can trigger hives
- Manage stress – Yoga, meditation, and counseling help lower stress and anxiety
- Stay cool – Overheating from hot showers, baths, and exercise can activate hives
- Wear breathable fabrics – Tight clothing can increase friction and sweat triggering hives
- Use gentle skincare – Harsh ingredients like fragrances may irritate skin and worsen hives
- Take antihistamines preventively – Your doctor may recommend OTC antihistamines before exposure to prevent hives
When hives are recurrent or the trigger is unknown, prescription preventive measures may be needed. Work closely with your healthcare provider to control discomfort and outbreaks.
When to See a Doctor to Fix Hives on Black Skin?
In most cases, OTC antihistamines and avoiding triggers can clear up mild acute hives within a few days. See your doctor if:
- Hives last more than 3-6 days
- Hives are widespread or painful
- Hives limit daily activities
- You experience angioedema swelling in the lips, face, or throat
- You have shortness of breath, dizziness, or fainting
- You have a fever over 101°F
These signs could indicate a severe allergic reaction that requires prompt medical treatment. Urgent care is also needed if chronic hives fail to improve with conventional treatments.
Living with Chronic Hives
Coping with chronic hives can be frustrating and isolating. Following these self-care tips may help:
- Learn your triggers – Keep a diary to identify potential hive triggers over time
- Find patient support groups – Connect with others who understand your daily challenges
- Lower stress through counseling, meditation, yoga, or Tai Chi
- Use phototherapy – Narrow band UVB exposure helps some patients
- Consider alternative medicine – Acupuncture, probiotics, and Chinese herbs may provide relief for some
- Notice patterns – Many patients experience worsening with their menstrual cycles
- Stick with treatment – It may take trials of different medications to find what works best
- Communicate with your doctor – Report any changes to your symptoms or side effects
While chronic hives can be frustrating, remissions do occur. Work closely with your doctor to find an effective treatment regimen.
Finding Providers Experienced in Treating Darker Skin
The first step to proper hive diagnosis and treatment is finding a dermatologist thoroughly trained to recognize skin conditions across all skin tones.
Here are some tips for locating high-quality dermatologic care for darker skin:
- Check credentials – Look for board certification in Dermatology from the American Board of Dermatology
- Search dermatology societies – The Skin of Color Society and Black Dermatologists Network directories list vetted providers
- Ask around – Talk to friends and family for local doctor recommendations
- Look for diversity – Diverse clinic staff and patient images on websites suggest cultural competence
- Query about experience – Ask prospective doctors directly about their experience with darker skin tones
- Go with your gut – Trust your instincts – if a doctor seems dismissive or unsure, move on
Finding a knowledgeable dermatologist you trust is critical for identifying and treating conditions like hives in darker skin. Don’t settle for sub-par care.
When to Go to the Emergency Room?
Severe hives have the potential to progress to a life-threatening allergic reaction called anaphylaxis. Seek emergency care immediately if you experience:
- Swelling of the lips, tongue, or throat
- Difficulty breathing
- Wheezing
- Dizziness, lightheadedness or fainting
- Rapid heart rate
- Severe stomach pain, nausea or vomiting
These are signs of a systemic allergic reaction that requires epinephrine and emergency medical treatment. Call 911 or have someone drive you to the nearest ER for urgent evaluation if these symptoms develop.
The Takeaway
While hives may seem easy to identify on pale skin, they can be trickier to diagnose on darker skin tones where redness is less apparent. Hives often manifest as subtle skin tone variations, texture changes, and itching or tenderness.
Many doctors lack sufficient training to recognize hives on darker skin, frequently leading to misdiagnosis. Finding a knowledgeable dermatologist you trust and advocating for appropriate treatment is key.
Acute hives often resolve with OTC antihistamines and trigger avoidance. Seek medical care promptly if hives are severe, widespread, or last more than a few days. Chronic hives may require prescription treatment to control flare-ups and discomfort.
With an accurate diagnosis and effective treatment plan, most patients with hives can manage symptoms and enjoy long periods of remission. Being your own best advocate is crucial for getting optimal dermatology care as a patient with darker skin pigmentation.
