What is the reason for itchy lumps on my body

In life, we often hear many people say that their skin is allergic and that red blisters will appear if they scratch it slightly. This is really annoying. Not only will it make you physically uncomfortable, but scratching for a long time will also cause your skin to break. At this time, it is necessary to find the cause of the disease in time and then receive treatment. So, what causes itchy bumps on your body? I will introduce you to the following content:

Do the bumps disappear on their own? If they do, it is considered a symptom of urticaria. Urticaria is mainly caused by low immunity, dysfunctional body functions, and some symptoms of blood toxins and blood heat in the body. When they accumulate in the body and are stimulated by external factors, they will flow down to the epidermis and cause this phenomenon.

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.

Clinical manifestations

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 disease 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.

1. Skin scratch urticaria/artificial urticaria

The patient's physiological response to weak external mechanical stimulation is enhanced, causing wheals on the skin. After scratching, or when wearing tight belts or garters, the patient will develop local wheals and itching.

2. Delayed dermatographism

Skin scratches will cause wheals and erythema 6 to 8 hours after stimulation, and the wheals will last for 24 to 48 hours. There is more than one delayed skin lesion, and small segments or dots are formed along the scratches. The lesions are deeper or wider, and even expand to both sides to form lumps. Local fever and tenderness.

3. Delayed pressure urticaria

The rash develops 4 to 6 hours after local skin pressure is applied and usually lasts 8 to 12 hours. Symptoms include localized, deep, painful swelling, which may be accompanied by chills, fever, headache, joint pain, malaise, and a mild increase in white blood cell count. Large local swelling resembles angioedema and is prone to occur on the palms, soles, and buttocks. There may be a 24-hour incubation period before the lesions occur.

When my body itches, bumps appear when I scratch it. After reading the above content, I learned that this might be urticaria. At this time, you must go to the hospital for examination and treatment in time. During the treatment, you must also pay attention to the care in your life, including eating habits, which will help the treatment.
