It is basically a group of skin conditions which can affect all age groups. The severity of the disease can vary. In mild forms the skin is dry, hot and itchy, whereas in more severe forms the skin can become broken, raw and start bleeding. Inspite of its unpleasant looks, eczema is not contagious. With proper medical treatment the inflammation of eczema can be reduced to a great extent. Eczema is primarily caused by irritants such as chemicals and detergents, allergens such as nickel, and yeast growths. In later years eczema can be caused by a blood circulatory problems in the legs. The causes of certain types of eczema remain to be explained. If you want to know more, you should probably get in touch with a good dermatologist. I’ve tried this site called mediangles and they seem to be pretty good. I’d suggest you check with them to get a second opinion.
