After taking a shower, I got red bumps on my body

Sometimes after taking a shower, small red bumps appear on my body. They are very itchy and the more I scratch them, the more itchy they become. If you don't scratch it, it will disappear automatically after about half an hour. Or after exercise, sweating may also cause such bumps. Sometimes it appears and sometimes it doesn't. In this case, it is generally suspected to be eczema. Eczema is a common skin disease that is prone to relapse and difficult to treat completely. Let me give you a detailed introduction to the clinical manifestations and treatment methods of eczema.

Clinical manifestations

1. According to the manifestation of skin lesions, 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.

treat

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 control principles

Look for possible triggers, such as work environment, living habits, diet, hobbies, thoughts and emotions, as well as the presence or absence of chronic lesions and internal organ diseases.

2. Internal therapy

Choose antihistamines to relieve itching, and use two together or alternately if necessary. Generalized eczema can be treated with oral or injected corticosteroids, but they should not be used for a long time.

3. Topical therapy

Choose appropriate dosage form and medicine 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.
