Small blisters on hands hurt when touched

Everyone's skin reacts differently to the external environment. Some people are more sensitive to the environment, so they are easily affected by it. For example, some people will develop small blisters on their hands in certain seasons. After these blisters go away, symptoms such as peeling and itching will appear. This may be caused by a lack of certain elements in the body. So what is the cause of painful blisters on your hands?

Many people develop blisters, itching and peeling on their hands in the summer. No matter how many methods they try, the problem remains unresolved and it recurs every year, causing them great distress.

This phenomenon is quite common and is medically known as dyshidrotic eczema. The cause of the disease is still unclear, and most people believe it is a nonspecific skin eczema-like reaction, which is related to personal constitution, autonomic nervous system dysfunction, and mental factors. The disease is characterized by repeated appearance of millet-sized papules and blisters on the palms and fingers, with no obvious inflammation around them. The blister walls are thick, and the blister fluid is transparent at first, but then becomes turbid. After 2 to 3 days, the blister fluid is absorbed by itself, and desquamation forms after drying, revealing pink new epithelium. Linear fissures form during flexion and extension of the fingers, and the rash is symmetrically distributed. The patient feels itching and burning pain in the affected area. Hot flashes are common in summer and can heal themselves without treatment in autumn. They can recur repeatedly for several years. There is no specific method for the prevention and treatment of this disease. In daily life, you should avoid spicy food, alcohol, coffee and other irritating foods, smoke less or no smoking, and use less or no alkaline soap, laundry detergent, and detergent to wash your hands. Do not prick blisters or tear the skin if they appear. Local treatment is mainly astringent and antipruritic, such as calamine lotion, 5% formalin or 1% methenamine, prickly heat powder, etc. If the blisters are obvious, you can use 0.5% aluminum acetate solution or 5% alum solution for soaking or wet compress. For those with obvious itching, corticosteroid preparations such as triamcinolone, compound Conal Cream, and chlorpromazine can be used. If the main symptoms are erythema, desquamation, and chapped skin, you can apply 10% urea cream, silicone cream, vitamin E cream, or salicylic acid ointment externally 1 to 2 times a month. Systemic treatment can be with antihistamines, vitamins B1, B2, A, and E. If the number of rashes is large and the subjective symptoms are obvious, a short course of oral corticosteroids such as prednisone can be used, 10 mg each time, 3 times a day, and the symptoms will be relieved after 5 to 7 days of continuous use. What are the characteristics of TCM treatment of dyshidrosis? Dyshidrosis not only affects the beauty of the hands, but also often affects the patient's life due to itching. In severe cases, secondary infection may occur, resulting in swelling and pain in the hands. Because the cause of this disease is not very clear, Western medicine has no satisfactory treatment to eradicate it. Traditional Chinese medicine has a long history of treating this disease. As early as the Ming Dynasty, it was called "ant nest". Since the symptoms are mainly deep blisters, it should be attributed to the dominance of dampness. Traditional Chinese medicine treatment is multi-faceted. Comprehensive internal and external treatment, combined with diet and emotional conditioning:
