Eczema causes the skin or scalp to itch and then the rash appears. Eczema usually appears on the face, neck, knees, arms, hands and feet but it can appear anywhere on the body. The affected areas are very dry, itchy, scaly and thickened skin. On light skinned people the skin appear reddish and later turns brown. On dark skinned people eczema causes pigmentation and later appears lighter or darker.
There is no cure for eczema, and the cause is not known. We feel that it is linked to an overactive response by our immune system to certain triggers. Extreme temperatures and certain foods can cause an allergic reaction and create a flare-up. Eczema can also be hereditary and commonly found in families with a history of asthma or allergies. For many wearing clothing made of rough material can cause the skin to itch. Using a certain soap and shampoo can cause a flare up; also detergents to wash clothes can create the skin to itch. For many coming in contact with animals can cause an outbreak. Other triggers can be an upper repertory infection and stress.
To control eczema, treatment is directed to relieve and prevent itching which can cause an infection. Since eczema causes the skin to get dry and itchy, lotions, creams and ointments are recommended to keep the skin moist. When the skin is damp after a shower or a bath, a topical application is used to retain the moisture. Cold pack can also be used to relieve the itching.
