Does Eczema Look Like Poison Ivy

Know When To See Your Dermatologist

Poison Ivy what does it look like? how to recognize it, rash

If you’re not sure what type of rash you’re suffering from, make sure you see your dermatologist for an accurate diagnosis. If it turns out to be poison oak or poison ivy, then there are a few telltale signs that you need to go back to your doctor for further treatment. If your rash persists for seven days or more, it’s time to call your dermatologist and get an appointment. In addition, any signs of infection, like blisters, fever, or swelling, require immediate medical care from your doctor or dermatologist. Even a mild rash can get infected if you’re not careful.

What Are These Small Itchy Blisters On My Fingers

Small, itchy blisters on the fingers, hands, and feet are often due to dyshidrotic dermatitis, a skin condition closely related to eczema. Dyshidrotic dermatitis typically begins suddenly as a cluster of vesticles that resemble tapioca.

Contact dermatitis can also cause small itchy blisters on your fingers or any part of your body. Blisters from contact dermatitis can be in clusters or individual blisters. They are often extremely itchy and break open easily.

Poison Ivy Rash Stages

After the skin comes in contact with the Urushiol Oil, itchiness marks the first stage of the condition. The affected skin region becomes very itchy. The affected person constantly scratches it to get rid of the itchiness.

The second stage is marked by the appearance of rashes. The rashes appear as red, swollen bumps on the skin. They can arise in a straight line or as streaks over the affected skin surface.

In the final stage, the blisters turn into vesicles filled with pus. These eventually burst to release a watery discharge.

    Poison ivy and other poison plant rashes cant be spread from person to person. But it is possible to pick up the rash from plant oil that may have stuck to clothing, pets, garden tools, and other items that have come in contact with these plants. The plant oil lingers on virtually any surface until its washed off with water or rubbing alcohol.

    The rash will occur only where the plant oil has touched the skin, so a person with poison ivy cant spread it on the body by scratching. It may seem like the rash is spreading if it appears over time instead of all at once. But this is either because the plant oil is absorbed at different rates on different parts of the body or because of repeated exposure to contaminated objects or plant oil trapped under the fingernails. Even if blisters break, the fluid in the blisters is not plant oil and cannot further spread the rash.

    Key Points About Poison Ivy Poison Oak And Poison Sumac

    • These plants cause an allergic reaction in nearly 85% of the population.
    • An oily substance in the plants called urushiol causes the allergic reaction.
    • The allergic reaction causes a rash followed by bumps and blisters that itch. Eventually, the blisters break, ooze, and then crust over.
    • The best treatment is avoiding contact with poison ivy, poison oak, or poison sumac.
    • There is no cure for the allergic reaction, but treatments can minimize the discomfort.

    Is Nummular Eczema Contagious

    No. You cannot catch nummular eczema or give it to anyone.

    This type of eczema tends to:

    • Develop on extremely dry skin

    • Appear after an injury like a cut, bug bite, or scrape

    • Be more common in people who already have one of these eczemas: atopic dermatitis, stasis dermatitis, or contact dermatitis

    When caught early and treated properly, nummular eczema can heal within 3 to 4 weeks.

    Nummular eczema

    This type of eczema often causes round, itchy spots on the hands, forearms, or lower legs.

    Once you have had nummular eczema, it can return. It tends to appear in the same place. Usually, something triggers it. Common triggers include stress, extremely dry skin, certain medications, or a hypersensitivity to something thats touching your skin.

    If you continue to have flare-ups, seeing a dermatologist can help. If you have a hypersensitivity, a dermatologist may be able to pinpoint it. Avoiding your hypersensitivity along with using proper skin care can prevent new flare-ups.

    Its also possible that those round, itchy spots are due to another skin condition. Ringworm and psoriasis can look like nummular eczema. A dermatologists trained eye can see the subtle differences on a persons skin.

    For any condition you may have, proper treatment can help ease your discomfort and reduce flare-ups.

    What Differentiates Eczema From A Reaction To Poison Ivy Or Poison Oak

    Dr. Brian Kim: Three things can often distinguish eczema from allergic contact dermatitis associated with poison ivy or poison oak. First, poison ivy/oak causes a hive-like eruption and then evolves into eczematous lesions. Eczema just flares into eczema, not hives. Second, poison ivy/oak tends to not respect typical eczema hot spots. You can see lesions in areas where the allergen was accidentally exposed, even the genitals. And therefore it will look more streaky, rather than a typical eczema distribution. Third, the blisters associated with poison ivy/oak are much more dramatic than those generally associated with classical eczema.

    Intense itching is another common symptom of eczemabut that could also be an allergic reaction or irritation from a new beauty product. So, how do you know the difference? Again, its important to note the location of the intense itch like the severely dry and sensitive skin, says Dr. Fromowitz. The biggest indicator is whether the itch develops before or after the presence of a physical rash. Eczema is known as the rash that itches, because you will likely get an intense itch that precedes the development of a rash. With contact dermatitis, or other forms of rashes, it is often the opposite: The rash appears before you get itchy. Heres how to tell the difference between eczema, rosacea, and psoriasis.

    Poison Ivy Poison Oak And Sumac Rashes

    Poison ivy, poison oak and sumac are plants that can cause redness, blotchy spots, itching, blisters and/or swelling upon contact.

    According to Mayo Clinic, poison ivy, poison oak and sumac rashes are caused by uroshiol, an oily resin that coats the plants.

    Although washing your skin immediately after exposure can help reduce your risk of getting a rash, the uroshiols oily nature can make it difficult to wash off.

    Over-the-counter washes designed to target uroshiol can be purchased at drugstores, but if youre not able to use such a wash before the rash sets in, theres little you can do besides treating the worst of the rashs symptoms.

    To soothe poison ivy, poison oak and sumac rashes, many turn to non-prescription anti-itch creams, which can help reduce itching. Other home treatments include cold compresses and oatmeal baths.

    People with severe rashes, blistering and swelling should see a medical provider and may be prescribed with a topical treatment.

    How Can I Prevent A Poison Ivy Rash

    The best way to avoid developing this itchy rash is by learning what poisonous plants look like so you can avoid them.

    If you think youve come in contact with a poisonous plant, you can:

    • Apply isopropyl alcohol to exposed body parts, gardening tools or other contaminated items to strip away the oil.
    • Scrub under your fingernails with a brush.
    • Use dishwashing soap and cool water to wash hands that have touched a poisonous plant.
    • Wash clothes after being outdoors.
    • Wear long sleeves, pants and gloves when doing yard work, gardening, farming or hiking.
    • Wear rubber gloves while bathing pets that have been in contact with poisonous plants.

    Poison Ivy Rash Vs Poison Oak Rash

    With spring gardening season just around the corner, its important to be mindful of rashes that occur with exposure to certain plants. Unlike viral skin rashes, poison Ivy, poison oak, and poison sumac contain a substance called urushiol that triggers an allergic reaction when it comes into contact with the skin.

    What do poison ivy and poison oak rashes look like?

    The resulting rash is red, itchy, often vesicular and may have a linear pattern. Regardless of which of these poison plants a person is exposed to, the rash is the same, because the allergen is the same. Typically, poison ivy is found east of the Rocky Mountains, poison oak grows west of the Rocky Mountains and poison sumac is more common in the southeastern United States or in wet, wooded areas in the northeastern United States.

    Poison Oak has been found in some eastern states however, it is very rarely found in the midwestern states. Poison ivy and poison oak both have three leaves and poison sumac has 7-13 leaves. Approximately 75% of people are sensitive to urushiol.

    How do you treat poison ivy and poison oak rashes?

    Treating poison ivy and poison oak depends on the location and severity of the rash and may include topical and oral antihistamines, topical and oral corticosteroids, and even antibiotics if infection develops from scratching this intensely itchy rash.

    Bed Bug Bites Versus Contact Dermatitis: What To Do

    If you are distinctly waking up at night with itching, swelling and red bumps on arms and legs the next morning, you must monitor the sleeping area for the pests. If you see other tell-tale signs of bed bugs, do call the Integrated Pest Control Services for getting rid of the bed bugs. Spot treatments, traps, sanitation and continuous evaluation are also necessary to prevent more bed bug bites.

    If however, you do not see any signs of the pests, but are still experiencing skin issues as those presented by contact dermatitis, please do not hesitate to see a dermatologist. S/he will evaluate if the condition is pruritis , scabies or an allergic reaction to some irritant. If however, s/he identifies the skin reaction as a bed bug bite, do take all necessary steps to prevent the situation from going out of control.

    The doctor will generally take a complete history in order to make a diagnosis of bed bug bites vs contact dermatitis. If another member of the family is also seen with similar bed bug bites then the result is clear. Also, if a patients parent has had similar reaction after having come in contact with an allergen or irritant then it is clearly contact dermatitis.

    Contact Dermatitis: Signs And Symptoms

    Contact dermatitis is a common skin condition that causes inflammation of the skin when the organ is exposed to an environmental agent. In contact dermatitis, the skin becomes red, itchy, swollen or inflamed when it comes in contact with certain substances. These substances can be classified into 2 types:

  • Allergens
  • Irritants
  • Allergens typically include adhesives, dyes and perfumes, nail polish, certain fabrics, metals like nickel, poison ivy, rubber, latex, gloves etc. Irritants include cement, hair dyes, pesticides, wet diapers, certain types of shampoos, weed killers and so on. Thus, the signs and symptoms of contact dermatitis vary from person to person depending upon whether s/he has been exposed to an irritant or allergen. These symptoms usually consist of one or more of the following:

  • Red bumps, rashes or oozing blisters
  • Swelling, pus formation, crusty appearance.
  • Redness, scaling, raw and tender to touch.

    How Does The Rash Show Up On The Skin

    It takes time for the rash to appear. A rash can develop in a few hours if youve had a rash from one of these plants before. If youve never had a rash from poison ivy, oak, or sumac, it can take 2 to 3 weeks before you see a rash.

    No matter how long it takes for the rash to appear, most people experience the following when they get a rash:

  • The skin itches intensely where the rash will appear. The itch can be so intense that it wakes you from a sound sleep.

  • Shortly after your skin starts to itch, the rash appears. Most people develop an itchy, red, and blistering rash.

  • If you have blisters, they break open and leak fluid.

  • The blisters crust over, and the rash clears in 2 to 3 weeks. The rash will clear without treatment, but it can be extremely itchy until it clears completely.

  • The intensity of the itch and severity of the rash can differ from person to person. Some people develop 1 or 2 small rashes. Others develop rashes all over.

    Dont Say ‘just Stop Scratching’


    When you have a bug bite, you can usually find a way to keep from scratching it. But eczema is different, says Kristin Capone, 23, of Westwood, NJ. âA bug bite is usually itchy in a small area. With eczema, it feels like every part of your body is covered in bug bites. Itâs a constant itch.â She says it even keeps her up at night.

    Tips For Identifying Poison Ivy

    How To Get Rid Of A Poison Ivy Rash Overnight

    A poison ivy rash may appear in straight lines. This is the result of plants brushing across your skin. The rash may no longer have those lines if you transfer the urushiol to your clothing or your hands and then accidentally spread it across your body.

    Symptoms typically begin to develop within a few hours or days after you come in contact with the plant. The more urushiol you come in contact with, the faster the reaction will be.

    Psoriasis can develop in one small area, or it can be widespread. Psoriasis patches are most common on the following areas:

    • elbows
    • feet
    • ankles

    Its less common but not impossible for rashes and plaques to develop on your scalp, face, and genitals.

    Unlike poison ivy, which typically goes away permanently after a few weeks with or without treatment, psoriasis will likely return. Thats because psoriasis is a chronic condition.

    Psoriasis is not always present for every person who has it. You may experience periods of inactivity. When this happens, the symptoms of psoriasis are mild or seem to disappear. Symptoms may return in weeks or months, or it may take years for the plaques to reappear.

    Acne Versus Skin Cancer

    Skin cancer can be difficult to identify from home. Because the appearance of acne can vary and skin cancers take on different forms on the skin, its easy to mistake one for the other.

    With something as serious as cancer, its important to get this right.

    Can skin cancer look like acne?

    Any pimple-like lesion in an adult that doesnt resolve or improve within 4 weeks should be evaluated by a dermatology provider.

    In the example below, the lesion on the left is an acne cyst. It looks very similar to the lesion on the right, which is a basal cell skin cancer, but they are very different and one is far more dangerous than the other.

    At-home diagnoses are difficult for those who arent sure what skin conditions present as what. When skin conditions arise, its always best to check with a board-certified dermatologist in order to ensure the best treatment plan.
