Eczema That Looks Like Hives

Coronavirus Rash Appears In Many Ways

My eczema sometimes looks like itchy bumps, like a bee sting. Do I have hives?

Many diseases, such as measles and chickenpox, cause a distinctive rash that helps doctors diagnose a patient. COVID-19 is different. There is no single COVID-19 rash.

What you may see: You can have COVID-19 and never develop a rash. When a patient with COVID-19 does develop a rash, it can look like any of the following:

  • Patchy rash

  • Blisters that look like chickenpox

  • Round, pinpoint spots on the skin

  • Large patch with several smaller ones

  • A lace-like pattern on the skin

  • Flat spots and raised bumps that join together

Symptoms: Some rashes itch.

Treatment: Some rashes require medical treatment.

Keep in mind that you can have a rash thats due to a condition other than COVID-19. If you develop a rash, contact your doctor.

Causes Of Discoid Eczema

The cause of discoid eczema is unknown, although it may happen as a result of having particularly dry skin.

When your skin is very dry it cannot provide an effective barrier against substances that come into contact with it. This could allow a previously harmless substance, such as soap, to irritate your skin.

It’s important to look carefully at all the chemicals in cosmetics and toiletries that may have come into contact with your skin. Contact dermatitis, a type of eczema caused by coming into contact with a particular irritant, may have a role in discoid eczema.

Some people with discoid eczema also have a history of atopic eczema, which often happens in people who are prone to asthma and hay fever. However, unlike atopic eczema, discoid eczema does not seem to run in families.

What Are The Basic Differences

Psoriasis is a chronic immune-mediated disease. That means your immune system becomes dysfunctional and chronically activated, resulting in skin changes. It causes raised, red, scaly patches on your skin or scalp.

There are multiple subtypes of psoriasis. Plaque psoriasis is the most common and accounts for nearly 80-90 percent of psoriasis cases.

People with plaque psoriasis typically have sharply demarcated, raised, itchy, painful red plaques covered with silvery scales. The plaques are most often found on elbows and knees, but they can occur anywhere.

Eczema is an inflammation of the skin that can have numerous triggers. Atopic dermatitis is the most common type of eczema. It typically occurs in people with a personal or family history of asthma, hay fever or other allergies, and it is often seen in children. It makes skin more sensitive and more prone to infection.

At any time in your life, you can develop eczema from dry skin or chemicals that contact the skin and trigger irritation or allergic reactions.

Neither psoriasis nor eczema is contagious, Dr. Fernandez says. But while you cant pass them from person to person, they may run in families.

Conditions That Can Look Like Eczema But Arent

Evan Starkman Brunilda Nazario, MD

Eczema is the name for a group of conditions that can make your skin irritated, inflamed, and itchy. Your doctor may call it atopic dermatitis, which is also the most common type of eczema. Youâre more likely to get eczema when youâre a child, but adults can get it, too.

The symptoms you have and where they show up on your body vary from person to person. You might have one or more of these signs:

  • Red patches on white skin
  • Gray or violet-brown patches on dark skin
  • Oozing or crusty skin from scratching
  • Swelling

Several health problems can bring on similar symptoms, so itâs important to talk to your doctor, a dermatologist, or an allergist to find out whatâs going on with your skin. They might tell you that you have one of these conditions that looks like eczema but isnât:

Psoriasis. This long-term condition is partly due to your immune system attacking your skin by mistake. Both psoriasis and eczema can bring on symptoms like:

  • Red, scaly patches
  • Dry, cracked skin
  • Itching

Eczema patches tend to be thinner than psoriasis patches. Another difference: Fluid can ooze from your skin with eczema.

Scabies. This contagious condition happens when tiny bugs called mites burrow into the top layer of your skin and lay eggs. You might have symptoms like bad itching and a rash that looks like pimples. Like eczema, you could also get scaly-looking patches.

Acne. This skin condition can take several forms, including:

Discoid eczema causes distinctive circular or oval patches of eczema. It can affect any part of the body, although it does not usually affect the face or scalp.

The first sign of discoid eczema is usually a group of small spots or bumps on the skin. These then quickly join up to form larger patches that can range from a few millimetres to several centimetres in size.

On lighter skin these patches will be pink or red. On darker skin these patches can be a dark brown or they can be paler than the skin around them.

Initially, these patches are often swollen, blistered and ooze fluid. They also tend to be very itchy, particularly at night.

Over time, the patches may become dry, crusty, cracked and flaky. The centre of the patch also sometimes clears, leaving a ring of discoloured skin that can be mistaken for ringworm.

You may just have 1 patch of discoid eczema, but most people get several patches. The skin between the patches is often dry.

Patches of discoid eczema can sometimes become infected. Signs of an infection can include:

  • the patches oozing a lot of fluid
  • a yellow crust developing over the patches
  • the skin around the patches becoming hot, swollen and tender or painful
  • feeling sick
  • feeling unwell

Emollients For Treating Eczema

Emollient creams add moisture to the skin. Apply moisturisers each day to clean, dry skin. It is especially important to moisturise after showering and bathing, and when living or working in an air-conditioned or heated environment. You may need to try several different brands until you find the emollient that works best for you. Ask your doctor, dermatologist or pharmacist for advice.

The Atopic March And Chronic Eczema

The atopic march describes how children with one allergic condition are at increased risk for others, and how allergic conditions tend to appear in a certain order .

Eczema and food allergies are both considered allergic conditions, and both are part of the atopic march. Babies usually develop eczema before food allergies, and infants with eczema are at increased risk for developing a food allergy.

This means that the order your babys symptoms appear can indicate whether your baby has eczema or food allergies. Eczema is usually the first to appear.

Most food allergic reactions like hives should go away within a few days or weeks, and by avoiding the allergenic or problem food, should go away altogether. On the other hand, eczema can often be a chronic condition and usually starts in infancy. Chronic eczema is the most common type of eczema and can be lifelong.

The order your babys symptoms appear can indicate whether your baby has eczema or food allergies. Eczema usually appears first.

When To See A Doctor If You Suspect Hives

Acute hives can be straightforward and may not require medical attention. But sometimes hives do warrant a visit to the doctor or the emergency room in severe cases. Its a good idea to visit your primary care doctor if you notice the hives continuing to appear over the course of several days or if you experience severe symptoms and discomfort. If the rash tends to pop up on and off again over a stretch of time, you may want to visit an allergist. He or she will likely run a skin-prick test to identify possible triggers that are causing the breakout.

Be on the lookout for more threatening symptoms, too. If you suspect angioedema , you should visit the emergency room immediately. You should also seek emergency care if the hives are associated with an allergic reaction and include other symptoms such as dizziness swollen lips, eyes, and tongue or anything that makes it hard to breathe. A good rule of thumb is that if youre having trouble breathing, go to the emergency room or call 911, Choudhury says.

What Are The Symptoms Of Hives

Hives are characterized by red or pale-colored welts on the skin, which typically come and go throughout the day, says Sourab Choudhury, DO, a dermatologist and the chief medical officer at the Dermatology Specialists, a private dermatology practice in New York City. Sometimes they itch, burn, or sting.

Usually the welts will be surrounded by clear edges. They may look similar to bug bites, but hives generally will appear and disappear more quickly. They may itch, sometimes severely, and theyre not always the same size or shape. They may be as small as the tip of a pen or as large as a dinner plate. When you press the center of a hive bump on the skin, it likely will turn from red to white, which is known as blanching.

Hives may appear on the body grouped together and take over a large area of the skin, or as a couple of individual welts that show up here and there. They can appear anywhere on the body, though some people get them in the same spot over and over again .

Generally, youll know you have hives simply by seeing the hives themselves. If you experience other symptoms, such as swelling in the eyes, lips, or inside of the throat, or if you have trouble breathing, you should call 911 or see a doctor immediately, says Sapna Palep, MD, a dermatologist at Spring Street Dermatology in New York City. These symptoms indicate you may be experiencing a serious allergic reaction called anaphylaxis.

What Are The Different Kinds Of Hives

Hives fall into two categories on the basis of the time they have been present: acute urticaria and chronic idiopathic urticaria . Since hives are so common and acute urticaria, by definition, resolves spontaneously, physicians do not generally expend much time or expense to evaluate the cause of hives of less than eight weeks’ duration.

Tips For Reducing Outbreaks

Here are a few ways to prevent eczema flare-ups and manage symptoms:

  • Apply cool compresses to your skin, or take a colloidal oatmeal or baking soda bath to relieve the itch.
  • Moisturize your skin daily with a rich, oil-based cream or ointment to form a protective barrier against the elements. Apply the cream right after you get out of the shower or bath to seal in moisture.
  • After you bathe, gently blot your skin with a soft towel. Never rub.
  • Avoid scratching. You could cause an infection.
  • Use fragrance-free detergents, cleansers, makeup, and other skin care products.
  • Wear gloves and protective clothing whenever you handle chemicals.
  • Wear loose-fitting clothes made from soft fibers, like cotton.

What Are Hives Treatment Options And Home Remedies

How to stop hives

The goal of treating most cases of ordinary acute urticaria is to relieve symptoms while the condition goes away by itself. The most commonly used oral treatments are antihistamines, which help oppose the effects of the histamine leaked by mast cells. The main side effect of antihistamines is drowsiness.

Many antihistamines are available without a prescription, such as diphenhydramine , taken in doses of 25 milligrams, and chlorpheniramine , taken in a dose of 4 milligrams. These can be taken up to three times a day, but because these medications can cause drowsiness, they are often taken at bedtime. Those who take them should be especially careful and be sure they are fully alert before driving or participating in other activities requiring mental concentration.

Loratadine and fexofenadine are antihistamines available over the counter that are less likely to cause drowsiness . Also approved for over-the-counter use is hydroxyzine , which causes drowsiness, and its breakdown product, cetirizine , which is less sedating.

Topical therapies for hives are available but are generally ineffective. They include creams and lotions which help numb nerve endings and reduce itching. Some ingredients which can accomplish this are camphor, menthol, diphenhydramine, and pramoxine. Many of these topical preparations require no prescription. Cortisone-containing creams , even strong ones requiring a prescription, are not very helpful in controlling the itch of hives.

Are Shingles And Eczema Contagious

Shingles is highly contagious to those who are not immune to the virus. Shingles can be transmitted through direct contact with sores, but a person who contracts shingles from an affected person will develop chickenpox, not shingles.

If you have shingles, in order to reduce transmission of shingles to others, ensure your rash is well covered, avoid scratching and touching the rash, wash your hands often, and avoid contact with at-risk people like pregnant women, those with weakened immune systems, individuals undergoing cancer treatment, and premature or low-weight babies.

Eczema, on the other hand, is not contagious and cannot be passed on from person to person. It is important to note if the rash becomes infected then the infection is contagious.

SSSS starts from a localised staphylococcal infection that is a producer of the two causative exotoxins . Outbreaks of SSSS often occur in childcare facilities. An asymptomatic adult carrier of Staphylococcus aureus introduces the bacteria into the nursery. About 15-40% of healthy humans are carriers of Staphylococcus aureus, that is, they have the bacteria on their skin without any sign of infection or disease . However, staphylococcal skin infections are seen commonly in infants and younger children, thus an obvious increased risk of SSSS. Staphylococcus aureus is also commonly found in infections of the throat, ears and eyes.
