What are the common symptoms of urticaria?
Symptoms of Urticaria
1. Chronic Urticaria
It is certain that skin rashes appear. Generally, if they last for more than two months or longer, they can basically be identified as chronic urticaria, and they appear several times a day or several days, and the time is uncertain. This kind of urticaria is more complicated.
2. acute urticaria
Most people who suffer from this disease often suffer from sudden redness, itching, and rashes of various shapes and sizes after eating seafood and medicines. They begin to show one piece at a time, and some gradually merge into a large piece. These urticaria rashes usually disappear within one day, but it is also possible to get rashes again. This situation will come one after another. Therefore, one of its most remarkable characteristics is its rapid occurrence and rapid decline.
Symptoms of urticaria
3. Artificial urticaria
is also called dermatoglyphics. It is when the skin is scratched with nails or blunt objects, a strip-shaped bulge consistent with the scratch occurs, and this strip-shaped bulge is accompanied by itching.
4. Peptone urticaria
This kind of urticaria is generally caused by food allergy, which is basically caused by peptone which is decomposed by protein in food. At first, the skin was congested, red and windy, accompanied by headache and fatigue. However, its course of disease is short, and it will subside within a few hours.
5. Cold urticaria
The attack is related to cold stimulation. After the patient is cold, if the skin is immersed in cold water, exposed to cold air or ice cubes, local skin edema and wheal appear, which can be divided into hereditary and acquired clinically.
6. Serum urticaria
is caused by handling blood, vaccination or drugs. The patient has fever, joint pain and lymph node enlargement, and the rash is common in annular wind mass. When accompanied by renal function damage, abnormal urine routine may occur.
7. Cholinergic urticaria
It is induced by exercise, eating hot drinks or food, sweating and emotional excitement. It is characterized by a small wind mass with a diameter of about 1-3 mm, with obvious redness around it, and sometimes satellite-like wind masses can be seen. Some patients may have abdominal pain, nausea, salivation, headache, dizziness and other systemic symptoms.
care for urticaria
1. Don't scratch with your hands
Most people's intuitive response to itchy skin is to scratch with their hands quickly, but you may not know that this action can not stop itching, and it may itch more and more. The main reason is that when you scratch the local area, it will increase the local temperature and release more histamine (allergen) in the blood, which will worsen.
2. Don't apply hot compress
Some people itch enough to want to apply hot compress. Although heat can temporarily relieve local pain, it is actually another stimulus. Because heat can make blood vessels tense and release more allergens. For example, some people who soak in hot springs or bathtubs in winter, or wrap themselves in heavy quilts are likely to cause urticaria.
3. Pay attention to finding allergens
In combination with previous medical history, if you find that you are allergic to a certain food or drug, you should stop using it immediately and take laxatives to promote the excretion of allergens in the intestine.
4. Avoid smoking and alcohol
Don't drink alcohol, including wine and beer, and don't smoke. Not only smokers themselves are allergic, but also passive smokers such as their children may be allergic.
5. Pay attention to diet
Eat more light foods rich in vitamins, and abstain from spicy food and aquatic products such as fish and shrimp. Encourage patients to drink more water, keep warm and keep their stools unobstructed.
6. Avoid fatigue
Urticaria patients should also pay attention to keep a good rest frequently to avoid excessive fatigue.
The harm of urticaria is serious, so once the disease appears, it must be treated in time to get rid of it as soon as possible.

1. Drug-induced: Most drugs are caused by allergic reactions. The common drugs are penicillin, furazolidone, serum products, vaccines, etc. Its onset has a certain incubation period. Drugs such as aspirin, morphine, atropine, vitamin B1 and polymyxin are histamine releasing agents, which can directly stimulate mast cells to release histamine and cause urticaria.
2. Food-induced: Mainly animal protein foods, such as fish, shrimp, crab, eggs, milk and other seafood, are common pathogenic factors. Some fruits and vegetables can also be sensitized. Adding condiments, preservatives and pigments in food, and natural or synthetic substances in food such as salicylic acid and citric acid can also cause urticaria.

4, such as bacterial infection, fungal infection, viral infection, parasitic infection, etc.
