Eczema can occurs acutely. However it is a chronic problem with acute flares. It is characterized by hot, red, itchy skin affecting either no particular area or the whole body.
Acute eczema presents as redness and swelling, papules, vesicles or large blisters, exudation and crusting and scaling.
Chronic eczema is less vesicular, more scaly but also pigmented and thickened and more likely to develop painful blisters.
