We know that patients suffering from urticaria will occasionally show red, swollen and itchy rashes on the face and limbs, most of which will subside after 2-24 hours. , but after subsiding, new rashes are repeatedly issued, and the rashes become more itchy with scratching. The number and frequency of
can not be determined. It can occur for several days at a time or several times a day. There are many causes of urticaria, and about a quarter of patients do not know their specific cause. can be insect bites, food, food additives, drugs, respiratory inhalants, sunlight, hot and cold body surface environment, endocrine disorders, mental factors, etc.
Urticaria is a very tormenting common disease, which has caused a great negative impact on people's body and mind. Urticaria is a skin disease. Will it spread to others due to contact with the patient’s skin?
First of all, we have to understand what is urticaria
Urticaria is a common skin disease. It is due to the temporary inflammatory edema of the blood vessels of the skin and mucous membranes under the influence of various factors, which causes a large amount of fluid to leak out. Resulting in local tissue damage. Urticaria is an allergic disease, so urticaria is not contagious. Therefore, do not worry about being infected when you come into contact with urticaria patients.
When urticaria occurs, the patient will first feel itching on the skin and then wind masses. This is the basic pathology of urticaria. The wind masses are mostly pale, with skin color and bright red. A small number of
also have edema erythema. The size and shape of the wind masses are variable, they can spread and merge, and they can merge into bullae. Occasionally a small number of patients with urticaria will have headaches, nausea, abdominal pain, diarrhea, etc. In severe cases, chest tightness, shortness of breath, increased heart rate, decreased blood pressure, weak pulse, pale complexion and other systemic diseases may occur.
There are many types of urticaria, in addition to acute urticaria and chronic urticaria, there are many special types, such as:
①Delayed skin scratch syndrome
After receiving scratch stimulation, the skin will appear in 6-8 hours. Red rash and wind mass. Delayed skin scratches are usually not one, , but many small segments and small spots appear along the scratch. There is tenderness, local redness and swelling.
②Delayed pressure urticaria
Urticaria appears after 4-6 hours of skin compression, which is manifested as deep swelling and pain of the skin. The onset of may be accompanied by chills, fever, headache, and general malaise.
③Skin scratches and urticaria
Patients respond to physical stimuli from the outside, causing wind masses on the skin.
④ Solar urticaria
When the skin is exposed to the sun, wind masses and erythema will appear quickly. is accompanied by symptoms of fatigue and chills.
⑤Contact urticaria
Skin contact with certain substances, there will be wind masses and erythema. Its mechanism can be divided into two types: immune and non-immune. Immune can detect IgE, which is type I hypersensitivity. non-immunity is that the direct irritation caused by the primary substance can cause disease, and all contacts will get sick, and no allergenic substance is needed.
⑥ Cholinergic urticaria
skin rash will occur in addition to the palm and plantar extensive small wind mass. Satellite-like wind clusters are occasionally seen. mostly occurs during exercise and shortly after exercise, taking away skin irritation such as itching, tingling, and burning sensation, which will be triggered by heat and skin irritation.
For patients suffering from urticaria, I have the following suggestions:
①Don’t go to scratch
People’s general intuitive response to itchy skin is to scratch with their hands, but for patients with urticaria, this action will not only stop the itching, but also return it. The more you scratch, the more itchy. Because the local temperature is increased when itching to the local area, makes the tissue release more histamine, which makes the urticaria worse.
②Pay attention to your diet
Do not eat marine fish, such as: hairtail, crab, yellow croaker, mussel meat, etc. Such foods are salty, cold and smelly, which can cause allergic diseases to people who are prone to allergies; vegetables include: bamboo shoots, spinach, mustard greens, pumpkins, etc., which are easy to induce skinSkin sore abscess; fruits mainly include: peaches, apricots, etc. Peaches are prone to scabies, sores, and carbuncle. Eating more apricots will cause carbuncle and furuncle, and hurt your muscles and bones.
③Do not apply hot compress
Although hot compress can temporarily relieve the local effect, it is another kind of stimulation. Because heat will strain the blood vessels, release histamine, which will aggravate urticaria. So you can't apply heat.
