Symmetrical occurrence on the palms and soles, deep in small blisters, occurring in batches, with tense blister walls, millet to rice-grain size, hemispherical and slightly raised above the skin surface, visible on the palms, sides and fingertips, with no inflammatory response.

2. The harm of small blisters on hands and feet

Dyshidrosis not only affects the appearance of the hands, but also often affects the patient's life due to itching. In severe cases, secondary infection may occur, causing swelling and pain in the hands. Because the cause of this disease is still unclear, Western medicine has no satisfactory treatment to eradicate it.

3. What should I do if small blisters appear on my hands and feet?

1. Do not scratch or squeeze them easily with your nails or other unhygienic objects, because once you break them, they will appear in groups next to the broken blisters. It can be said that they are contagious to a certain extent, and if they are broken by unhygienic objects, they may cause infection.

2. Keep your hands clean and dry. You can wash your hands with sulfur soap properly because it has a bactericidal function. However, when using sulfur soap, be careful not to wear valuable items such as silver jewelry on your hands, otherwise it will react chemically with the sulfur soap, causing the silver jewelry to turn black and deteriorate.

3. In terms of diet, eat less spicy and irritating foods, such as chili peppers, hot pot, fish and shrimp, etc., and eat more fresh fruits and vegetables. Avoid contact with irritating substances such as laundry detergent and dishwashing detergent.

4. Soak your hair in 9°-12° vinegar for about half an hour every night before going to bed. Let it dry naturally after soaking. Do not rinse with clean water, otherwise the effect will be reduced. If you continue soaking for about half a month, you will see good results and your skin will start to crack, and you will be almost healed after the cracking.
