Contact dermatitis is an inflammatory response when your skin is reacting to an allergen or irritant. This can happen 24 to 48 hours after contact, according to the New York Times Health Guide. Common offenders that trigger the burning, itchy rash are cleaning chemicals, laundry detergents, lotions, poison ivy, nickel and rubber.
Avoid the Allergen or Irritant
This may not be as easy as it sounds, as sometimes it's hard to determine the allergen. Try to remember any new substance with which you have come into contact over the last one or two days. Perhaps it was a new soap, lotion, laundry detergent or even a piece of jewelry. Where is the rash--on your arms, where you applied a lotion, on your neck, where you wore your new necklace? Once you have determined the trigger, discontinue using that item. In the future, test any new product on a small area of your skin before using it to avoid a significant reaction.
Wash the Area and Protect Yourself.
After coming into contact with something that you know causes dermatitis, thoroughly wash the area with mild soap and water to remove all remnants of the substance. Wear protection before handling any product that may cause a reaction. If you're using cleaning products, for example, wear rubber gloves.
Medication and Creams
In most cases, the dermatitis resolves itself in a few days. In more severe cases, your doctor might order a corticosteroid cream or anti-itch cream to help relieve the symptoms. In cases where a large area is affected, or symptoms are severe, an oral medication may be needed. Talk to your doctor about the treatment that's appropriate for you.
Other Measures
A moist dressing may relieve the itching and burning. Wet a clean towel in cool water. Apply throughout the day. Taking a cool bath can also be soothing. Try to wear clothing that has a smooth texture to minimize symptoms.
