What's the matter with the red pimples on the waist

Diseases are very common in people's daily lives. For example, skin diseases and red bumps on the waist are very common diseases. However, many people are very confused when they experience this disease. They don't know what causes this disease and what methods should be used to treat it. What is the cause of the red bumps on the waist? Let us find out.

First, what is the matter with the red bumps on the waist? This is a case of urticaria allergy. Be careful not to scratch it, as the more you scratch it, the more bumps will appear. In this case, you can apply some Bactroban or take Claritin, try to drink more water, supplement more vitamin C, and avoid spicy and irritating foods. And also pay attention to enhancing immunity, which can reduce allergies. Urticaria is commonly known as wheal. It is a localized edema reaction caused by dilation of small blood vessels and increased permeability in the skin and mucous membranes. It usually subsides within 2 to 24 hours, but new rashes may occur repeatedly. The course of the disease lasts from several days to several months. It is quite common in clinical practice.

Second, the cause of urticaria is very complicated, and the cause cannot be found in about 3/4 of patients, especially chronic urticaria. The common causes include: food and food additives; inhalants; infection; drugs; physical factors such as mechanical stimulation, cold and heat, sunlight, etc.; insect bites; mental factors and endocrine changes; genetic factors, etc. The basic lesion is the appearance of wheals on the skin. The skin often itches first, followed by the appearance of wheals, which are bright red or pale, skin-colored. A few patients have edematous erythema. The size and shape of the wheals vary, and the onset time is uncertain. The wheals gradually spread and merge into sheets. Due to edema of the dermal papillae, the openings of the epidermal hair follicles can be seen sunken downward. The wheal lasts from several minutes to several hours, and in some cases it can last for several days before disappearing without leaving any trace. The rash occurs repeatedly in batches, mostly in the evening. Wheals are often generalized but may also be localized. Sometimes it is accompanied by angioedema, and occasionally bullae form on the surface of the wheal. Some patients may experience nausea, vomiting, headache, head swelling, abdominal pain, and diarrhea. Severe patients may also have systemic symptoms such as chest tightness, discomfort, pale complexion, accelerated heart rate, weak pulse, low blood pressure, and shortness of breath. A disease that is cured in a short period of time is called acute urticaria. If the urticaria recurs at least twice a week for more than 6 weeks, it is called chronic urticaria. In addition to the common urticaria mentioned above, there are also the following special types of urticaria.

What causes the red bumps on the waist? Skin scratch urticaria or artificial urticaria is caused by the patient's enhanced physiological response to weak external mechanical stimulation, which produces wheals on the skin. After scratching, or when wearing tight belts or garters, the patient will develop local wheals and itching. Delayed dermatographism: Wheals and erythema appear 6 to 8 hours after stimulation, and the wheals last for 24 to 48 hours. There is more than one delayed skin lesion, and small segments or dots are formed along the scratch. The lesions are deeper or wider, and even expand to both sides to form lumps. Local fever and tenderness.
