What is the reason for blisters on my left hand

In our lives, many mothers often find blisters on their babies' hands, and this phenomenon mostly occurs in summer, because in summer the weather is hotter and the sun is more scorching. If the baby sweats frequently, it is likely to cause some sweat herpes, which is a common skin eczema disease. So what is the reason for the blisters on the left hand?

Dyshidrosis is a type of skin eczema that occurs symmetrically on the sides of the hands or feet. Because it occurs in the limbs where sweat glands are particularly active, and blisters are the primary manifestation, it is named sweat herpes. Most people believe that the cause of the disease is a non-specific skin eczema-like reaction, which is related to their own 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 relatively thick, and the blister fluid is clear at first, then becomes turbid. After 2 to 3 days, the blister fluid is absorbed on its own, and desquamation occurs after drying, revealing pink regenerative epithelium. Linear fissures form during flexion and extension of the fingers, and the rash is distributed symmetrically. 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, and can easily recur for several years.

1. Factors causing blisters on hands

1. Excessive dampness and heat in the body causes small blisters and slight itching on the hands. Chinese medicine believes that when dampness and heat rise in the body, it will be reflected in the body. Usually these small blisters are translucent or opaque and usually slightly itchy.

2. Caused by some fungi. Because summer is here, many people like to cool down and wash their hands in cold water or touch something with a cool surface. It is usually accompanied by some fungi, and then small blisters appear with varying degrees of itching.

3. Allergy. Some people with sensitive skin may be extremely sensitive and may also develop small blisters on their hands.

2. Characteristics of small blisters on the hands

1. The occurrence of dyshidrotic eczema has a significant seasonality. It often occurs at the turn of spring and summer and heals itself in winter. It is mainly seen in young people.

2. It is now generally believed to be a skin eczema-like reaction, which is related to factors such as severe mental state, hyperhidrosis of hands and feet, fungal infection and allergic reaction.

3. Deep small blisters, the size of millet to rice grains, slightly higher than the skin surface, often without redness. Symmetrical occurrence on the palms and soles, deep in small blisters, occur in batches, with severe blister walls, millet to rice-sized, hemispherical and slightly higher than the skin surface, can be seen on the palms, sides and tips of the fingers, with no inflammatory reaction. After the blisters dry up, they peel off to reveal new skin, often accompanied by varying degrees of itching and burning sensation.

4. Dyshidrotic eczema often recurs regularly every year. Dyshidrosis occurs symmetrically on the palms, soles, and fingers (toes). After 1-2 weeks, it dries up into flakes and may recur, accompanied by varying degrees of burning sensation and itching, often occurring for several years.

3. The harm of small blisters on the hands

Dyshidrotic eczema 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 yet clear, Western medicine has no adequate treatment to eliminate it.

4. Introduce simple and effective maintenance methods

Medicines and equipment that need to be kept at home: a bottle of iodine, a box of cotton swabs, foot light powder, white vinegar, and peppercorns. Detailed explanation:

1. People whose hands are prone to sweating must always keep their hands clean and dry and wash their hands frequently, which can reduce the number of blisters.

2. Before blisters develop on your hands, soak your hands in a solution of white vinegar diluted in warm water for five minutes every day, which has a sterilization effect. Or you can use heated and diluted alum and then soak your hands or feet to stop sweating. Soaking your hands in this way frequently on hot days can prevent blisters on your hands.

3. When blisters have started to form on your fingers, use the tip of a needle dipped in iodine to puncture the blisters, then absorb them with a cotton swab. Then use the cotton swab dipped in iodine to rub the punctured blisters several times. Spread your five fingers so that they do not touch each other. Usually, scabs will form the next day. (Remember not to let the water from the blisters get on other skin, otherwise other parts will be infected)

4. When there are many blisters on the palms and they are itchy, soak your hands in hot water with a light diffuser. Most of the blisters on the palms will break. After soaking, dry your hands and then wipe them with iodine. Dry your hands in the sun. Most of the blisters on your hands will turn into white skin the next day and you can just wait for them to fall off by themselves. (Just soak your feet once or twice. The skin on your hands is thin so it is not suitable to soak your feet frequently.)

5. Boil water with peppercorns, and then wash with the peppercorns water, once in the morning and once in the evening. Be sure to put more peppercorns. It is best to have enough water on the surface of the container. Boil it, and wash it after it cools down a little. It must not be too cold. It is best to use light scalding. Wash more where there are bubbles. Finally, rub the bubbles with the boiled peppercorns. It doesn't matter if they break. Peppercorns are the best for sterilization.

5. How to prevent and treat blisters on your hands

There is no specific way to prevent and treat 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 or tear the skin when blisters appear. Some treatments are mainly to astringe and relieve itching. If the itching is severe, you need to go to the hospital for a check-up.
