Rash

stock_14.jpgRashes appear when the skin has mild redness, small red bumps, and in severe cases, redness, swelling and blisters. Many rashes are caused by skin irritants and can also be classified as contact dermatitis. Contact dermatitis occurs when your skin comes in contact with an irritant and becomes inflamed. The itchy rash is not contagious. There are many substances that can cause irritation, including soaps, make-up, certain metals used in jewelry, or plants such as grass, weeds, poison ivy or poison oak. Once you determine what is causing your rash, avoid coming in contact with it. The rash should clear up in 2-4 weeks. Meanwhile, you can use anti-itch creams to relieve your skin.

In other cases, rashes appear in conjunction with a viral infection, a fungal infection, a bacterial infection, exposure to certain bugs, or exposure to extreme heat.
