A lot of "small blisters" suddenly appeared on my hands. What happened?

As the temperature rises, some people find that they have more and more blisters on their hands, which causes some trouble in our lives.

Some people even encounter "little blisters" almost every year, but they don't know what they are called or what causes them. Today I will take you to learn about these "little blisters".

What are blisters?

The small blisters we refer to in daily life are actually dyshidrotic eczema, also known as dyshidrotic eczema. It is a recurrent blistering skin disease that is mostly seasonal, usually beginning in late spring and early summer, aggravated in summer, and getting better in winter.

The disease often occurs on the palms, sides of fingers, and fingertips.

The typical manifestation of dyshidrotic eczema is rice-sized blisters that are hemispherical, slightly higher than the skin surface, appearing several or in groups, with little obvious redness around them, and are usually itchy.

The blisters of herpes zoster have the following characteristics:

Blisters usually occur in groups and are symmetrical on the hands and feet.

The blisters have thick walls and contain clear fluid, which may be accompanied by varying degrees of itching or burning.

Blisters generally do not burst on their own. After 2 to 3 weeks, they will dry up and peel off, revealing thin and tender skin, which may cause pain.

Dyshidrotic eczema will recur, and sometimes new blisters will occur before the old blisters have healed.

Why does sweat herpes occur?

It is currently believed that dyshidrotic eczema is a type of eczema and has little to do with excessive sweating of the hands and feet, although patients often have excessive sweating of the hands and feet, and controlling sweating can relieve it.

Studies have found that some patients are allergic to metals such as nickel and chromium, which falls into the category of systemic contact dermatitis. Some people also come into contact with laundry detergents, soaps, detergents, etc., which can cause skin lesions to worsen.

Is dyshidrotic eczema contagious?

Since dyshidrotic eczema is an inflammatory disease and is not contagious, breaking the blisters will not lead to infection. However, pinching the blisters will cause skin damage, and the hands often come into contact with various things, which increases the risk of infection. Therefore, pinching the blisters is not recommended.

How to treat dyshidrotic eczema?

For early blisters, you can use topical glucocorticoids, such as mometasone furoate cream and halometasone cream. For later skin lesions that peel and dry, you can use vaseline ointment, vitamin E urea ointment, etc.

When itching is obvious, you can take antihistamines orally, such as chlorpheniramine, levocetirizine, etc.

For a small number of patients with severe conditions that seriously affect their life and sleep, short-term use of glucocorticoids may be considered.

What should we pay attention to in daily life?

For patients with dyshidrotic eczema who sweat a lot on their hands and work in a humid environment, keeping their hands dry is beneficial to the condition. Therefore, patients can appropriately reduce the frequency of hand washing and reduce contact with water.

For patients with dandruff, you can apply some simple moisturizing cream after washing your hands every time.

Patients with dyshidrotic eczema should try to avoid or reduce contact with laundry detergent, soap, dishwashing detergent, etc. to reduce skin irritation.

Patients with dyshidrotic eczema should try to avoid scratching when they feel itchy. When the itching is severe, they can apply a wet, cold compress to the affected area to help relieve the itching.

People with dyshidrotic eczema should avoid direct contact with acidic foods, such as citrus fruits.
