Itchy skin, this is reliable

Due to the complex causes of itching, the current medical understanding of the physiology and pathology of itching is superficial, so that we have all kinds of "pain-relieving tablets" and "pain-relieving tablets", but there are no "anti-itching tablets" and "pain-relieving tablets". Itching tablets". The current antihistamines, that is, the familiar anti-allergic drugs such as chlorpheniramine and astemizole, can prevent the irritation of histamine on the skin, and therefore have a certain antipruritic effect, especially for allergies such as urticaria. For skin diseases, the effect of antipruritic is more obvious. But in fact, the cause of itching is not only histamine, but also other inflammatory mediators. Many medical diseases, tumors, and neurological abnormalities can all cause itching. Therefore, for itching caused by other diseases, anti-allergic drugs have less obvious anti-itching effect. Therefore, antihistamines cannot be taken as antipruritic drugs.

Is there no way to deal with tormenting itching? Of course there is. The best way is to cure the skin itching, and the itch will disappear when the disease is cured. Most skin diseases have symptoms of itching, but the causes of these skin diseases and the causes of itching are not exactly the same. Only symptomatic treatment under the guidance of a doctor can cure the disease and suppress itching. Secondly, topical application of appropriate drugs can quickly and temporarily relieve itching, and it is also a commonly used method of anti-itch. However, external medicine should not be used indiscriminately. For example, some anti-itch syrups contain a certain amount of alcohol. For skin diseases with redness, swelling and fever, the more local congestion and swelling are used, the heavier the swelling; if the ointment is applied to the skin sore with erosion and water , As the exudate of the wound surface cannot be absorbed or evaporated, the erosion surface will be enlarged. Hormones have a strong anti-inflammatory effect, so ointments containing corticosteroids have a strong antipruritic effect, but if patients with beriberi and tinea corporis use it as an antipruritic medicine, the fungus will grow more vigorously under the action of hormones. Make the condition worse and prolonged. Generally speaking: calamine lotion, pine pollen, etc. can be used for skin lesions with redness and heat without erosion and exudate. By soothing and protecting the local skin, it helps the inflammation of the sporadic lesions to accumulate heat to relieve itching; redness and erosion The skin lesions can be treated with 3% boric acid aqueous solution and Chinese medicine Portulaca oleracea decoction as a cold and wet compress to clean the skin lesions, distribute inflammation, store heat, and inhibit exudation to stop itching. For some chronic skin diseases, where the local skin is thick and rough, various ointments can be used. The sealing effect of the ointment can be used to isolate external irritation, maintain the moisture in the skin, and soften the skin to relieve itching. Therefore, there is no anti-itch medicine that can suppress all itching in external medicines. The appropriate treatment medicine must be selected according to the condition of the disease. Anti-itch medicine must not be used indiscriminately. Since itching is an unpleasant sensation transmitted by nerves, for severe itching, sedatives can also be taken to relieve itching by reducing the sensitivity of the nervous system to itching. However, due to the addictive nature of sedatives and the damage to the nervous system caused by long-term use, do not use them lightly

In addition to general skin diseases that often cause skin itching, many medical diseases also often cause skin itching, such as: liver and gallbladder disease, diabetes, renal failure, hyperthyroidism, nervous system disorders and neurological dysfunction, vitamins, trace elements and other nutrient deficiency, There are also malignant tumors that can cause skin itching, and sometimes this itching is even serious and difficult to control. Therefore, if there is unexplained intractable pruritus, you should take this as a clue to do a comprehensive physical examination to detect hidden diseases as soon as possible. Indiscriminate use of antipruritic drugs will only cover up the symptoms and delay the condition.
