I believe that many people have tried the skin with sudden wind and prickly rashes, "a tart" like a mosquito bite red rash everywhere, the more scratches, the more scars, and it is out of control.
It turns out that when we have been exposed to allergens, the cells of the body will produce an inflammatory response, leading to the onset of acute wind disease, and even life-threatening in severe cases.

Don't want to be swollen by the wind and face, remember not to be disturbed, and be patient with the treatment. At present, most of the antihistamine drugs can control the condition and restore the skin without scars or paralysis.
Dr. Lin Jiawen, a specialist in dermatology, pointed out that the treatment of wind disease must maintain patience, and various behaviors that make the disease worse should be avoided in daily life.
The medical name of wind disease is urticaria, which is divided into acute and chronic.
Acute wind disease is mainly induced by specific factors, such as food, drugs, mosquito bites, infections, temperature and emotional stress. The onset lasts for less than 6 weeks, and it resolves spontaneously every time it lasts for several hours to several days; chronic wind disease There is a chance to appear every day or often, the skin will swell, be surrounded by ring-shaped erythema of different sizes, and feel burning, and it can last for 6 weeks or more, affecting the patient's daily routine and mood.
Acute wind disease usually resolves on its own within a few days, but it can be a sign of a severe allergic reaction. If you encounter the following conditions, it must be treated as soon as possible.
Acute wind disease causes skin rashes of varying sizes and extremely itchy skin.
Symptoms of allergic reactions:
-Swelling of lips, eyelids and entire face, itchy throat and palms of hands and feet
-Swelling of the trachea and throat, causing wheezing and difficulty breathing
-Abdominal pain, nausea and vomiting
-Feeling dizzy, fainted, and unconscious
-shock
However, there are various fallacies about wind disease in the market. For example, they believe that the skin is directly blown by the wind, or the blood gas moves too fast after a meal or bath.
In fact, most of the causes of chronic wind disease are unknown, while acute wind disease is usually triggered by allergens.
When our own immunity decreases and we are exposed to allergens, the concentration of immunoglobulin IgE in the body will increase. After contact with mast cells, the cells will release histamine and inflammatory factors, causing rashes and itching such as mosquito bites. And angioedema.
Wind disease allergens: peanuts, seafood, milk and MSG
These allergens are common in our living environment. For example, peanuts, seafood, milk and monosodium glutamate are common food allergens. Blood pressure medicine, painkillers and aspirin can all cause acute wind disease, clothing friction or Too tight may also induce allergic reactions.
Patients must be careful not to scratch the affected area to stop the scar, otherwise the rash will become larger and larger; some patients may even use essential oils or ointments to relieve itching, but this will not improve the condition and will cause contact dermatitis.
Don't underestimate the sequelae caused by wind disease. If the disease is too serious, the patient's mouth and face will swell, the trachea will be narrowed to breathing difficulties, and even life-threatening.
The most important thing is to seek medical attention as soon as possible and formulate a corresponding treatment plan according to the condition: For patients with relatively mild symptoms, antihistamine drugs can already control the condition. As the drugs improve, these drugs will no longer cause eye drowsiness. Patients are advised to follow Medications are used regularly; patients with serious illnesses may need to inject biological agents to help eliminate itching and rashes, but beware of side effects such as sinusitis, headaches and arthritis.
Avoid long blowing heaters in winter can cause dry skin
To prevent the onset of wind disease, patients can undergo a blood test to determine whether the condition is caused by food or other diseases.
In daily life, try to reduce the consumption of MSG, spicy and irritating foods and stale foods, and avoid various factors and behaviors that may worsen the condition, such as scratching, taking a hot bath, wearing tights, wearing a necklace, and Blowing the heater in cold weather can cause dry skin, etc.
However, patients with chronic wind disease need long-term medication, and remember to maintain patience and compliance with the treatment.
Examples of common allergens:
-Food: milk, eggs, nuts, soybeans, cereals, seafood
-Drugs: non-steroidal anti-inflammatory analgesics, aspirin, antibiotics, etc.
-Pets: hair, dander
-Additives: MSG, preservatives
-Clothing: the clothes are rubbed or too tight
