Have you ever had a red, itchy rash that does not go away? Chances are, it may be eczema. While mild eczema is not life threatening, it may be extremely uncomfortable with an itch. Symptoms usually vary depending on the individual, and may include dry, scaly, red and itchy skin. If left untreated, constant scratching may lead to bleeding, crusting, or broken skin open to possible infection. It is usually easily diagnosed by doctors by a physical check-up, and most of the time, does not require biopsies or additional testing.

According to the National Eczema Association, the term "eczema" is a general term used to describe dermatitis and can be interchangeably used. Although it comes in many forms, eczema mostly describes a dry skin condition that may be relieved by moisturizers and emollients.

The most common symptom of eczema is red, swollen and itchy skin. The symptoms may vary depending on the specific type of eczema you are dealing with.

These outbreaks can appear practically anywhere on the body, and the location of the affected area can be used to classify the particular type of eczema that the person is suffering from.

Unfortunately, there is no known treatment for eczema, but there are many ways to relieve symptoms. For example, there are several easy home remedies that can help relieve itch and irritation should a breakout take place.
