If you have this form of skin rash it is imperative that you do not scratch it because it could lead to an infection.

Allergic Dermatitis

This type of dermatitis happens when the skin is in contact with a form of an allergen of sorts. In some cases you can notice an itchy, red rash, this happens when the immune system thinks what you have come into contact with is a foreign body. The only real way of preventing this form of dermatitis from affecting you is by finding what products irritate your skin and stay away from them. Usually, the substances that trigger this type of dermatitis are poison ivy, particular metals, perfumes, certain food items, some soap, detergents, shower gels, chemicals and some cosmetic products. The longer period of time the substance is on your skin the worse the rash will become. The symptoms are severe itching coupled with swelling and plenty of inflammation.

Nummular Dermatitis

Small papules are what characterize this form of dermatitis. They begin as patches of skin that are itchy and then form small lumps which produce an oozing liquid after which they heal over as a crust. At this point, they can turn into lesions. This type of dermatitis can cause the host to experience sever burning and itching and the cause is still unknown although it seems the dry weather can start it up on occasion. This rash can be seen on the arms, legs and torso.
