There are individual differences in how long it takes for seasonal allergies to heal on their own, and no generalizations can be made. Seasonal allergies are mostly related to pollen and plants in the spring and fall and can manifest as urticaria, such as scattered wind clusters or wind-blown erythema and papules all over the body. Some patients may develop dermatitis eczema, with common symptoms such as erythema, papules, papules, exudation, and even vesicles, accompanied by significant itching. Patients are advised to go to the allergist department of the hospital to check for allergens and identify the specific substance to which they are allergic. The symptoms usually subside in 2-3 days after the allergen is removed, but in some patients with severe disease, it takes 1-3 months for the allergic symptoms to significantly reduce or subside. Patients should maintain a balanced nutrition during the illness, consume more fresh vegetables and fruits to strengthen skin resistance, avoid saltwater fish, shrimp, crab and other allergy-prone foods, and reduce going out.
