Irritant contact dermatitis typically causes burning and pain at the exposed area. Itching is the main symptom of allergic contact dermatitis. Irritant contact dermatitis will more commonly cause dry, cracked skin, while allergic contact dermatitis can form fluid-filled blisters.
Contact dermatitis can be diagnosed by a primary care physician or dermatologist based on the physical appearance of your skin and reported symptoms. The best way to prevent irritant contact dermatitis is to:. If you suspect you may have an allergy to a certain substance, your doctor can perform skin patch testing , where patches that contain small amounts of common allergens are applied to the surface of your skin.
These patches are typically applied to your back or arm and left in place for 48 hours. During this time, you should avoid bathing, showering, swimming, and activities that cause a lot of sweating. Irritated skin at the site of application may indicate an allergy to a particular substance that you should avoid contact with. Allergic contact dermatitis localized to a specific area can be treated with topical steroid creams such as triamcinolone 0.
They can reduce pain and inflammation within 12 to 24 hours. Oral prednisone should generally be tapered off over the course of two to three weeks to prevent rebound dermatitis that can come back with sudden discontinuation of the medication. While generally not effective for alleviating itching from allergic contact dermatitis, the antihistamines Benadryl and Vistaril may provide some symptom relief.
You should see a doctor if you think you have a skin allergy so that you can have patch testing performed. If your patch testing comes up positive for a skin allergy, your doctor can prescribe topical or oral steroids to treat your contact dermatitis. Irritant and allergic contact dermatitis can worsen with a bacterial infection. If your rash has exudate or pus, weeping, or crusting, schedule an appointment with your doctor to receive further treatment.
Dyshidrotic dermatitis is a form of eczema that causes small fluid-filled blisters to form on your hands and feet, causing the skin to crack, scale, and flake.
This condition can result from a variety of different causes, including atopic dermatitis, allergic contact dermatitis, systemic allergic reaction, fungal infection, excessive sweating called hyperhidrosis , or as a side effect of intravenous immunoglobulin therapy.
The exact cause of dyshidrotic dermatitis is not fully known. Dyshidrotic dermatitis blisters can be itchy or painful, but typically resolve over time as the blisters dry up and the skin peels and falls off.
Dyshidrotic dermatitis can be diagnosed by a primary care physician or dermatologist based on the physical appearance of your skin and symptoms. Patch testing may be performed to see if you have an allergy to a particular substance. Dyshidrotic dermatitis can be managed by avoiding exposure to known irritants and treated with topical or oral steroids. When treatment for dyshidrotic dermatitis does not improve symptoms after two to four weeks, further testing should be performed to determine if a different condition is causing your symptoms.
A biopsy of your affected skin area can determine if there is a bacterial, fungal, or viral infection causing your symptoms that requires further treatment. Neurodermatitis is a form of eczema that causes thick, dry, leathery patches of skin that itch. It is similar to atopic dermatitis, and is often triggered by stress or other types of eczema. Skin patches caused by neurodermatitis can occur anywhere on the body, but occur most commonly on the arms, legs, shoulders, elbows, ankles, hands, and wrists.
Sometimes your face and genital region can be affected as well. Itching can come and go, and can vary in intensity. Neurodermatitis can also cause pain and hair loss if the scalp is affected.
While the cause of neurodermatitis is unknown, itching often begins or worsens during times of increased stress, anxiety, or depression. Even when periods of stress stop, the itching can continue. Effectively managing stress can help prevent and decrease the severity of neurodermatitis symptoms.
Neurodermatitis rarely improves without treatment, and requires treatment with topical steroids, oral antihistamines, and products like moisturizers and coal tar to reduce skin redness, swelling, itching, pain, and dryness.
Neurodermatitis patches can become infected. If your skin lesions are particularly painful or do not improve in two to four weeks with steroid treatment, you should see your doctor to determine if you have a skin infection that's delaying the healing process. Nummular dermatitis , also called nummular eczema and discoid eczema, causes itchy, coin-shaped round patches of skin. It occurs most commonly on the arms and legs but can also affect the hands, feet, or body.
Because of the round appearance, it can be mistaken for ringworm or psoriasis. While the cause of nummular dermatitis is unknown, it often occurs in people with dry skin where there is an increased permeability of the skin to allergens.
Nummular dermatitis is also associated with interferon and ribavirin therapy for treating hepatitis C and tumor necrosis factor inhibitor medication used to treat autoimmune diseases. Tiny bumps and blister-like sores may appear after you injure your skin. For example, a scrape on the back of one knee could trigger nummular eczema bumps on the backs of both knees.
If you have a darker skin tone, your patches may appear brown. Dermatologists in particular can help identify which type or types of eczema you may have and how to treat and prevent flare-ups.
