What are the dangers of scratch disease

Scratch disease, also known as skin scratch disease, means that if the skin is accidentally scratched, there will be an obvious red and swollen mark. Scratching disease is generally divided into two types, one is physiological, which is caused by physical abnormalities. Another type is allergic, which is a symptom that occurs after the skin is irritated. Below, we will introduce in detail the symptoms, causes and treatments of scratch disease.

symptom

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.

Causes

The internal cause of skin scratches is an allergic constitution. The most common allergens causing skin scratches are drugs, especially penicillin, serum preparations, as well as bacteria, fungi, plant proteins, animal proteins, etc.

Many people ignore the treatment of tinea pedis. You should know that the metabolites of various fungi that cause tinea pedis often act as strong allergens. After being absorbed by the body, an antigen-antibody reaction will occur, which will result in skin scratching.

To cure skin scratches, of course, you must first eliminate allergens, conduct antibacterial and antifungal treatments, avoid drug allergies, and avoid eating fish, shrimp, and shellfish. You also need to change your allergic constitution.

There are many external factors as well. Factors such as diet, inhalation, climate, and contact allergies are the most common causes of skin scratches. Due to such complex reasons, skin scratching disease recurs due to the interweaving of numerous causes and inducing factors.

treat

Simple therapeutic dermatographism generally does 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.
