1, itching is unbearable, which seriously affects sleep and leads to drowsiness and fatigue during the day.
2, repeated attacks, lingering is difficult to heal, eczema is easy to repeat, and improper treatment in the acute stage is easy to turn into subacute and chronic eczema. Chronic eczema can lead to acute attack if it is not handled properly.
3, exudative: seen in acute eczema and subacute stage, or acute episode of chronic eczema.
4. Polymorphism of rash: Rash includes papules, papules, blisters, erosion, exudation and other primary damage, which can cause scratches, bloody scars and other secondary damage due to scratching.
5, symmetry, generalized: eczema can be limited to a certain part of the body, such as ears, scrotum, hands and so on. , but also all over the body. Eczema is easy to diagnose, but difficult to treat. Generally, comprehensive therapy should be adopted, and both Chinese and western medicines should be taken orally and externally. If it is not treated properly, it is easy to aggravate the condition.
Psoriasis: commonly known as psoriasis. Psoriasis is called "boils" in Chinese medicine, which is a common chronic, recurrent and inflammatory skin disease. It is characterized by papules and erythema of different sizes on the skin, and the surface is covered with silver scales, which can affect the whole body. Some patients have seasonal aggravation, which is characterized by easy recurrence or aggravation in winter and spring and remission in summer and autumn. The etiology of psoriasis is still unclear. At present, psoriasis is considered to be the result of the interaction between genetic factors and environmental factors. Psoriasis can be divided into three types: psoriasis vulgaris, arthropathy, pustule and erythroderma, among which psoriasis vulgaris accounts for more than 99%, and other types are mostly induced by local irritating drugs, systemic use of glucocorticoid and immunosuppressants, sudden withdrawal of drugs, infection and mental stress. The treatment of psoriasis adopts different treatment methods according to different types. First, inform patients to reduce mental burden and try to avoid all kinds of inducing factors. At present, various methods to treat psoriasis can only achieve short-term curative effect, but can not prevent recurrence. Psoriasis vulgaris is harmless to the body. Never blindly pursue thorough treatment and use drugs that can cause serious adverse reactions (such as systemic use of glucocorticoids and immunosuppressants). ) to avoid aggravating the disease or transforming into other types.
Acne: commonly known as acne, acne, acne and facial sores in ancient Chinese medicine. It is a chronic inflammatory skin disease involving sebaceous glands of hair follicles, which often occurs in sebum overflow area and can be manifested as acne, papules, pustules, nodules, cysts and scars. Young men and women are more common, mostly in the head, face, neck, chest and back and other parts rich in sebaceous glands. The etiology of acne is complex, which is mainly related to the increase of androgen and sebum secretion, abnormal keratinization of sebaceous ducts in hair follicles, and the proliferation and inheritance of Propionibacterium acnes. The incidence of some patients is also related to heredity, immunity, use of cosmetics, dietary stimulation and endocrine disorders, which are manifested as familial aggregated acne, fulminant acne or acne attacks related to menstrual cycle. The treatment principle is to remove fat, dissolve keratin, sterilize, diminish inflammation and regulate hormone level.
Athlete's Foot: (especially athlete's foot) is the most common superficial fungal disease, which is widely prevalent all over the world, with a high incidence in summer and autumn, and is often manifested as severe in summer and mild in winter or mild in Xia Dong. Skin lesions spread from one side to the other. According to the clinical characteristics, tinea manuum and pedis can be divided into three types: blister scale type, hyperkeratosis type and erosion type. Tinea pedis (especially erosive type) is prone to secondary bacterial infection, pustular ulcer, acute lymphangitis, lymphadenitis, cellulitis or erysipelas, and can also cause tinea rash when the inflammatory reaction is obvious. Therefore, attention should be paid to the timely and thorough treatment of superficial mycosis to eliminate the source of infection; The disease is mainly treated with drugs, and sticking to drugs is the key to successful treatment. The course of treatment is generally 1 ~ 2 months. For tinea manus and pedis with hyperkeratosis or those with poor curative effect of external use, oral administration may be considered.
Herpes zoster: caused by varicella-zoster virus, it is characterized by small clustered blisters distributed along unilateral peripheral nerves, often accompanied by obvious neuralgia. Skin lesions are arranged in bands along peripheral nerves, mostly on one side of the body, and generally do not exceed the midline. Neuralgia is one of the characteristics of this disease. Can appear before the onset or accompanied by skin lesions, elderly patients are often more intense.
Neuralgia after herpes zoster: Herpes zoster is often accompanied by neuralgia, but it usually disappears after the skin lesions completely subside or within 65,438+0 months. A few patients have neuralgia lasting for more than 65,438+0 months, which is called post-herpetic neuralgia and is the most common complication. The principle of treatment is antivirus, analgesia, anti-inflammation and prevention of complications as soon as possible.
Warts: The common clinical warts are verruca vulgaris, verruca plana, verruca plantaris and condyloma acuminatum. Epidermal dysplasia verrucosa is also considered to be closely related to human papillomavirus infection. The source of infection of this disease is patients with virus and healthy people, mainly through direct or indirect contact. The virus enters the body through slight damage to the skin mucosa and replicates and proliferates, resulting in benign epithelial vegetation. People are generally susceptible, and people with low immune function and trauma are prone to this disease. External medication and physical therapy are mostly used for this disease, while oral medication is mostly used for patients with large skin lesions or patients who need long-term treatment.
Urticaria: commonly known as "rash", it is a localized edema reaction caused by reactive expansion and permeability increase of small blood vessels in skin and mucosa. I retreated when I was hiding, leaving no trace. This disease is relatively common, about 15% ~ 25% people have it at least once in their lives. Most patients cannot find the exact cause, especially chronic urticaria. The causes of urticaria, especially chronic urticaria, are very complicated, and we should investigate them one by one while excluding systemic diseases, such as changes in the surrounding environment, seasonal climate, mental stress, digestive tract dysfunction, drug factors, chronic infection focus or other systemic diseases. In the course of treatment, it is very important to remove the cause.
Itching is a kind of skin disease with only itchy skin and no primary skin lesions. The cause of this disease is very complicated. A variety of internal and external factors can cause systemic itching, among which internal factors include individual skin traits, neuropsychiatric factors, systemic diseases (such as liver and kidney diseases, blood system diseases, endocrine and metabolic diseases, infectious diseases such as malignant tumors and parasites, and some chronic diseases), pregnancy, drug or food allergies, etc. External factors include environmental factors (such as season, temperature, humidity, light, working and living environment, etc.). ) and living habits (such as soap, cleaning skin care cosmetics, wearing clothes, etc. ). Some primary skin diseases can also cause localized itching, such as vulvar itching and scrotal itching caused by infection (fungi, trichomonads, crabs, etc.). ), clothing irritation and drug irritation, as well as perianal itching caused by hemorrhoids, anal fissure and pinworm infection. For the treatment of itching, we should first make clear whether there are systemic diseases, treat them in time, avoid local irritation, including scratching, scalding and improper treatment, and avoid eating irritating food; Topical and oral drug therapy
