Skin allergy yellow discharge

The human skin is actually quite fragile. Although it is a protective barrier, it is also very prone to various problems. For example, bruises may easily appear when it is bumped. Eating certain foods or touching certain things may also cause skin allergies. If it is just a mild skin allergy, it is not particularly troublesome, but skin allergy with yellow discharge is a more serious symptom. Why is this happening?

Eczema is a skin inflammatory reaction with severe itching caused by a variety of internal and external factors. It is divided into three stages: acute, subacute and chronic. (1) Acute eczema lesions initially appear as numerous densely packed millet-sized papules, papulovesicles or small blisters with a flushed base that gradually merge into patches. Due to scratching, the tops of the papules, papulovesicles or blisters may be scratched to reveal obvious punctate exudation and small erosive surfaces with unclear edges. If secondary infection occurs, the inflammation will be more obvious and may form pustules, pus scabs, folliculitis, furuncles, etc. Conscious severe itching. It often occurs on the head, face, behind the ears, distal limbs, scrotum, and perianal area, and is often distributed symmetrically. (2) Subacute eczema After the inflammation of acute eczema is alleviated, the skin lesions are mainly small papules, scabs and scales, with only a small amount of papulovesicles and erosions. Still have severe itching. (3) Chronic eczema often turns into chronic eczema due to repeated attacks of acute or subacute eczema. It may also start as chronic eczema. The symptoms include thickening and infiltration of the skin in the affected area, brown-red or pigmentation, rough surface, scaling, or scabs due to scratching. Conscious itching. It is commonly found in the calves, hands, feet, elbows, popliteal fossa, vulva, and anus. The course of the disease is uncertain, prone to relapse, and difficult to heal.

2. According to the scope of skin lesions, it is divided into two categories: localized eczema and generalized eczema. (1) Localized eczema occurs only in specific parts of the body and can be named according to the part of the body, such as hand eczema, vulvar eczema, scrotal eczema, ear eczema, breast eczema, perianal eczema, and calf eczema. (2) Generalized eczema has multiple lesions that spread or scatter to multiple parts of the body. Such as nummular eczema, autosensitive eczema, and xerotic eczema. The causes of eczema are complex, and it is easy to recur even after improvement through treatment, making it difficult to cure. Because the clinical morphology and location are unique, the medication varies from person to person.

1. General prevention and treatment principles: Look for possible causes, such as work environment, living habits, diet, hobbies, thoughts and emotions, as well as the presence or absence of chronic lesions and visceral organ diseases. 2. For internal treatment, use antihistamines to relieve itching. If necessary, use two types of drugs in combination or alternately. Generalized eczema can be treated with oral or injected corticosteroids, but they should not be used for a long time. 3. For external treatment, choose appropriate dosage forms and drugs according to the condition of skin lesions. For acute eczema, local washing and wet compresses with normal saline, 3% boric acid or 1:2000-1:10000 potassium permanganate solution, and calamine lotion for astringency and protection. Subacute and chronic eczema should be treated with appropriate glucocorticoid creams, tar preparations or immunomodulators, such as tacrolimus ointment and pimecrolimus ointment. Add antibiotic preparations for secondary infection.
