What are the symptoms of atopic eczema at different stages?

Many people do not understand that atopic eczema, also known as atopic rash or allergic rash, has an important relationship with genetics. Patients with allergic constitutions, if they usually eat protein-rich foods, or come into contact with pollen and dust, etc., are prone to some symptoms, which often lead to skin flushing, erosion and exudation, unbearable itching, etc. For children, it will cause developmental abnormalities.

(1) In infancy, the disease usually begins one month after birth and often occurs on the cheeks. It presents as eczematous changes, with local redness, erosion, exudation, and crusting, and the patient feels severe itching. It is usually acute or subacute. The lesions can spread to the entire face, scalp, and in a few children, the neck, extensor side of the limbs, buttocks, etc. Usually it heals itself within 1 to 2 years of age, but in some cases it may persist into childhood.

(2) The eczema persists during childhood or infancy or recurs after a few years of relief, and there are also cases with no history of eczema in infancy. The rash can be divided into two types:

① Prurigo type: It often occurs on the extensor side of the limbs, mainly scattered millet-sized normal skin color or brown-red papules, clustered or scattered, with severe itching, often accompanied by scratches and blood scabs. The disease progresses slowly with repeated attacks and enlarged inguinal lymph nodes. This type of disease is more common in preschool children. If the illness lasts for a long time, the nutritional development of the child is often affected.

② Eczema type: It is more common on the flexor side of the limbs, especially the elbows and armpits, followed by the face and neck. It presents as subacute eczematous lesions with mild moist exudation, or localized lichenification, which forms erosion, exudation, and crusting after scratching. The course of the disease is chronic, with frequent recurrences. Traditional Chinese medicine calls it Four-Way Wind.

(3) In adulthood, the disease presents as disseminated neurodermatitis, which is more common in the elbows, axillae, and flexor sides of the limbs. Frictional stimulation may cause exudation and crusting, and the disease may also spread throughout the body. Conscious itching.
