The exact cause of eczema is not known for sure but some believe that it can be the result of a genetic predisposition; however, there are others who claim external factors are a contributing cause. This skin complaint causes the sufferer many problems but the constant itchiness must cause considerable irritation plus the skin becomes very red and extremely dry. This dryness can lead to what appears to be a ‘crusty' surface that may exhibit blistering.

Whilst a number of forms exist, the most common is the form of atopic eczema; this too is known, like the rest, to have a severe itching symptom. The main problem with the itching, especially with atopic eczema is that scratching brings relief but at a cost of intensifying the condition. Unfortunately a serious side effect is the skin becomes much more sensitive; sufferers avoid contact with soaps and washing powders but other man-made items such as make-up can have the same effect as well.

In many instances when young children have this condition it is only seen as an area under the skins surface. Although the primary factor with eczema is itching you might still be susceptible to normal rashes; if this ‘itchiness' is not present in a person who suffers with the condition then it is unlikely to be a symptom of it. However, if the itching has been somehow improved by eczema treatment but the rash has not, then the rash may not be related to the itch.

Because itching is a symptom in many problems related to the skin, including this skin disorder, this is not the basis of diagnosing the condition. Eczema itching and rashes go hand in hand but medical science still can't full explain why the skin itches the way it does. Another symptom is redness so when your blood flow increases, the skin becomes very red.

Eczema inflammation can have many triggers and more about this is being discovered constantly; one such cause can be the result of bacterial infection. Sufferers also exhibit blisters quite frequently which are normally quite small although bigger blisters are sometimes visible; this could be caused sufferers that have developed an infection in that area or as a result of their genes. Most often, the blisters seen as a symptom are filled with fluid; great care is required not to make matters worse (by scratching) than they already are.
