"Skin Writing Board"

This is a special type of allergic urticaria that generally manifests as a strong physiological response

Often the skin is itchy or burning first, and after scratching, scratching or rubbing, a wheal is generated, which looks like an improvised relief work

It can occur in people of any age, and children are no exception, and there are two main types:

Simple skin scratches

It occurs in 2% to 5% of the population, which means that about 5 out of every 100 people will develop the disease

When the skin is physically stimulated, wheals develop within 6-7 minutes, begin to subside after 15-30 minutes, mostly without itching or other discomfort, which is often considered a physiological response

Symptomatic skin scratches

This is common in young people with allergies, usually within 5 minutes and lasts for 30 minutes, and the skin in the affected area will not only appear typical erythematous wheals, but also accompanied by itching, in addition to inflammation and swelling reactions

Why does artificial urticaria arise?

It is mainly due to the allergic reaction of the skin after being physically stimulated by the outside world, so that the mast cells release histamine substances, causing the skin capillaries to dilate, so that plasma and tissue fluid penetrate into the dermis layer

The disease is usually idiopathic and does not have a clear stimulus, so the causes of induction are complex

For example, some simple movements (scratching, rubbing clothes, leaning on solid objects, etc.

Although most of the symptoms appear to be caused by intentional scratching, patients are often unaware of this behavior, and sometimes dry skin or idiopathic pruritus can cause the patient to scratch the skin, which in turn causes skin scratches

How should it be treated?

Studies have shown that in patients with chronic urticaria, 36% of artificial urticaria will disappear in about 5 years, 51% will disappear in about 10 years, but some patients will have a lifelong presence or intermittent recurrence

Treatment of simple skin scratches

If there is simple skin scratching disease that is non-itching, it generally does not require treatment, just avoid exposure to irritants
.

Treatment of symptomatic skin scratches

If it is symptomatic skin scratches, it is really itchy and intolerable, antihistamine drugs can be taken, such as cetirizine, loratadine, etc.
, if necessary, a combination of drugs, in general, the vast majority of
patient symptoms can be relieved.

In addition, daily life also needs to do a good job of prevention, try to avoid the use of bath towels; Choose comfortable and loose clothes
.

If the skin is relatively dry, it is recommended to apply emollient in time after bathing every day to moisturize to avoid aggravation
of the disease.
