The typical clinical manifestations of spring urticaria are skin itching first, and then red or white wheals. The location of the wheals is variable, and they vary in size and shape. They can be heavy and light, and appear and disappear. The common ones are about the size of a fingernail or a nickel, slightly higher than the surrounding skin. The lesions are dense at the beginning, slightly red around the edges, slightly white in the center, with clear boundaries, usually round or oval, spreading to all sides, and may be mutual. Blended into sheets, it appears in an irregular map shape and can spread throughout the body.
Things to note:
1. Pay attention to your diet and avoid triggers. The onset of urticaria has a certain relationship with diet, and certain foods may be triggers. For example, fish, shrimp, seafood, canned foods, pickled foods, beverages, etc. containing artificial colorings, preservatives, yeast and other artificial additives can induce urticaria. In addition, irritating foods such as too sour and spicy will also reduce the digestive function of the gastrointestinal tract, causing food residues to stay in the intestines for too long, thus producing peptone and peptides, increasing the chance of human allergies.
2. Pay attention to allergies caused by drug factors. In clinical practice, some drugs can cause urticaria, such as penicillin, tetracycline, chloramphenicol, streptomycin, sulfonamides, polymyxins and other antibiotics, metamizole, aspirin and other antipyretic analgesics, etc. Certain Chinese patent medicines such as Ganmaoqing and Niuhuang Jiedu Tablets can also cause allergies and cause the onset of urticaria. When you are taking multiple drugs and suspect that your urticaria is caused by one of the drugs, the simple and effective way is to stop taking the drug in time (go to the hospital immediately for treatment under the guidance of a doctor).
3. Pay attention to hygiene and prevent adverse stimulation. People with a history of urticaria should pay attention to keeping indoors and outdoors clean and hygienic, and keep fewer pets such as cats and dogs at home. Prevent inhalation of pollen, dust, etc. Avoid wind, cold, heat, dampness, dryness, fire and insect poison. Adapt life patterns to changes in the external environment. Drinking alcohol, being exposed to heat, being impulsive, and exerting force will aggravate the dilation of blood vessels in the skin and aggravate or aggravate the condition. Rubber gloves, hair dyes, perfumed soaps and detergents, chemical fiber and woolen clothing, etc., may be harmful irritants to people with allergies or urticaria patients and should be avoided.
