Hi,
This could be an
eczema or atopic dermatitis. The term
eczema is broadly applied to a range of persistent skin conditions. These include dryness and recurring skin rashes which are characterized by one or more of these symptoms: redness, skin edema (swelling), itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding.
It is basically a skin inflammation which is caused due to genetic predisposition and environmental factors, allergy being the most important factor.
