Artificial urticaria symptoms

Friends who have experienced skin allergies know that urticaria is the most difficult skin disease to cure among all skin allergy symptoms. When urticaria occurs, it is not only extremely itchy, but also spreads quickly. Once scratched, a large area will appear. It will disappear on its own after taking some anti-allergic drugs. There are many factors that cause urticaria, which may be caused by food allergies or some allergens.

In recent years, the incidence of artificial urticaria has shown an increasing rate year by year. Dermatographism is also called artificial urticaria. Urticaria is divided into acute urticaria and chronic urticaria. Both are allergic reactions of the skin, which are extremely itchy and the affected area is wheal-like. So what are the symptoms of artificial urticaria? How to identify artificial urticaria? Let’s share it below.

Methods/Steps

1. There are two types of skin scratches: one is called simple skin scratches, which is more common in women and is a physiological abnormal physical reaction. The symptoms are wheals that appear after the skin is scratched by nails or other blunt objects, most of which do not cause itching or other discomfort.

Another type of skin scratching is called symptomatic skin scratching, which is common in young people with allergic constitution. The cause of its occurrence is mostly due to the allergic reaction of the skin after external physical stimulation, which causes mast cells to release biologically active substances such as histamine, causing the skin capillaries to dilate, the permeability to increase, and the plasma and tissue fluid to penetrate into the dermis. People suffering from this skin scratching disease often feel itchy skin for no reason, but unlike the common urticaria, they do not have wheals all over the body. Instead, when the skin is scratched with nails or other blunt objects, erythematous wheals appear locally first, and then the wheals swell up above the skin, and red halos appear at the edges of the erythematous wheals. Their shape is very similar to the marks left after the skin has been whipped with a whip. Some patients with severe symptoms may even experience swollen lips after their lips are bitten by teeth.

2. Simple therapeutic skin scratches generally do not require treatment. For symptomatic skin scratch disease, the causative factors should be found and eliminated as much as possible. For example, patients who are taking penicillin should stop taking penicillin immediately; those with bacterial infections should receive anti-infection treatment; those with fungal infections such as tinea pedis can receive anti-fungal treatment, etc. Secondly, antihistamines such as chlorpheniramine and antalol can be used, which have certain therapeutic effects. In addition, some drugs that reduce the permeability of blood vessel walls, such as vitamin C, calcium supplements, etc., can be used as an auxiliary. It is worth noting that penicillin should not be used to treat patients with skin scratches who also have other infectious diseases.

3. The scratch reaction is when a blunt and hard object such as a toothpick is used to scratch the skin. A triple reaction of red lines, redness and edema will gradually appear at the scratched area. It manifests as clear linear raised wheals accompanied by unbearable severe itching. If the patient scratches, the wheals will expand and merge along the scratches, eventually forming large wheals. There will be no wheals where there is no scratching. Once the patient stops scratching or falls asleep, the wheals will quickly disappear, leaving no trace after they subside. However, in a very small number of patients, the symptoms are exactly the opposite. Wheals and severe itching appear first, and then the characteristics of scratching appear. This is called symptomatic scratching.

The above is a brief introduction to the symptoms of artificial urticaria. I believe that through the simple introduction above, everyone has a preliminary understanding and knowledge of the symptoms of artificial urticaria. Therefore, patients must pay attention to finding allergens in their daily lives, eat less spicy foods, and it is best not to eat seafood. They can eat more fresh fruits and vegetables.
