I recently developed these extremely itchy blisters on my body. They are not mosquito bites, but skin diseases.

Itch is the main theme of summer

I can't get rid of mosquitoes and midges.

I'll give you a bite if you're okay.

More than just itching

Psychologically, it is more like "scratching the skin and itching"

I just want to pick

However, this is not the most annoying itch.

If you have recently

A dense patch of small blisters

You may have herpes

Those who have experienced it understand

This thing itches.

I really can't stand it

Let’s first get to know dyshidrotic eczema. It usually grows on the palms and fingers , and once it grows, it grows in a large area, like a bunch of small water droplets.

At the same time, sweat herpes also has these characteristics:

◆ Symmetrical disease;

◆ The blisters contain blister fluid, which may cause itching and burning sensation;

◆ The blisters will generally dry up and peel off after 2 to 3 weeks, exposing the skin, which may be painful;

◆ Recurrent attacks.

Important! Dyshidrotic eczema will recur . Don’t think that if it is cured this time, it will not recur next time. You may get it back at the same time next year.

However, there is no need to worry that it will be like psoriasis and cannot be shaken off. Dyshidrosis is generally more common in young and middle-aged people and will not occur often when you are older.

Thinking about it this way, dyshidrotic eczema seems to have its benefits. At least it proves that you are still young.

There are some rumors that once the blister breaks, the blisters will grow wherever the water inside flows, and if they accidentally touch other people, they can be contagious.

Don’t believe this kind of thing, dyshidrotic eczema is not an infectious disease!

In essence, dyshidrotic eczema is an eczema-like skin reaction and can be considered a special type of eczema.

So it also has the characteristics of eczema, such as itching. In this type of inflammatory skin disease, inflammatory mediators will stimulate the peripheral nerves of the skin, and itching is unavoidable.

But like other eczema, it only itches yourself and not others, and it is not contagious.

Although it cannot be accidentally transmitted to others, studies have found that:

There may be some familial clustering of dyshidrotic eczema.

So it is still possible that it runs in your family.

In addition to genetic factors, these factors may also induce sweat herpes:

● Allergic reactions;

● Mental stress or anxiety;

● History of eczema;

● Personal constitution is sensitive to humidity and temperature changes;

● Contact with irritants, such as some chemicals;

● Excessive sweating of hands.

Therefore, if you really want to prevent hyperhidrosis of hands, you might as well start from these aspects: keep your hands clean, relax your mind, avoid irritation, and keep them dry.

The advice is to avoid picking if you can.

Although scratching it won't cause any immediate consequences, breaking the dyshidrosis rash will cause skin damage . Hands are one of the parts of the body that are most likely to come into contact with bacteria and viruses. Don't let the dyshidrosis rash itself get infected even though it's not a big deal.

As for how to deal with dyshidrotic eczema, the simplest way is actually to endure it!

Dyshidrotic eczema is a self-limiting disease that usually heals itself in about half a month.

If you can endure it for a while, everything will be fine. As long as you get through the most itchy period, it will surrender on its own.

If the disease does not heal for a long time or becomes infected or festering, you should seek medical treatment promptly.

Of course, the method of endurance is not suitable for everyone. After all, not everyone can bear the itching of dyshidrotic eczema.

So, is there any way to make it less itchy?

In general, you can try applying calamine lotion externally . If the blisters are found to be damaged or eroded, it is not recommended to use it forcefully.

There are also some topical medications that can be tried, such as corticosteroid creams or ointments, triamcinolone acetonide urea ointment, etc.

I would like to remind everyone that if the situation is out of control, you should consult a doctor first and ask for medicine. It is always better than doing it yourself.
