Itchy bumps appear on the body when scratched

If you feel itchy and get bumps when scratched, this may be due to skin problems. It is a type of urticaria that mainly produces papules on the skin and mucous membranes. It is also a common symptom of skin disease in daily life. There are many causes of the disease in daily life, mainly due to some children's food, some common medicines, and some types of infections. External stimulation or physical and mental factors can cause the sudden onset of this disease.

Generally, in terms of diet, we mainly adopt some dietary health care and medication treatment. Try not to eat spicy and irritating foods in your life. From the perspective of prevention and treatment of urticaria, we must find the exact factors and some pathological causes in order to more correctly eliminate the disease.

1. Foods such as fish, shrimp, eggs, and milk are the most common, followed by meat and certain plant foods such as strawberries, cocoa, and tomatoes. In addition, spoiled food decomposes into polypeptides, and alkaline polypeptides are histamine releasers. Protein foods are absorbed in the form of peptones or polypeptides before being completely digested, which can cause urticaria. This is more common in children and may also be due to the different permeability of the digestive tract mucosa in children and adults. In addition, coloring, flavoring, preservatives, and natural or synthetic substances added to food can also cause urticaria.

2. Drugs can be divided into two categories. One category is drugs that can form antigens, such as penicillin, serum, vaccines, sulfonamides, furazolidone, etc., and the other category is histamine releasers, such as aspirin, morphine, codeine, pethidine, polymyxin, vitamin B, quinine, hydralazine, etc.

3. Infection Various infectious factors can cause this disease. The most common ones are viruses that cause upper respiratory tract infections and Staphylococcus aureus, followed by hepatitis, infectious mononucleosis and coxsackievirus; parasitic infections such as ascariasis, hookworms, schistosomiasis, filariasis, amoeba and malarial parasites; bacterial infections such as acute tonsillitis, alveolar abscess, sinusitis, impetigo, sepsis, etc.

4. Inhaled pollen, dust, animal dander, smoke, feathers, fungal spores, volatile chemicals (such as formaldehyde, acrolein, pyrethrum, cosmetics, etc.) and other airborne allergens.

The above are the common manifestations and treatment methods of bumps on the body when scratched. There are also many causes of the disease in daily life, mainly due to some children's foods, some common medicines, and some types of infections. External stimulation or physical and mental factors can cause the sudden onset of this disease. We must actively carry out prevention and treatment and develop good hygiene habits and good eating habits.
