Allergic bumps are considered atopic dermatitis or urticaria, which are treated mainly with anti-allergic therapy with slight differences in treatment. In allergic dermatitis, the rash persists and can gradually expand. Urticaria can fade on its own, leaving no trace after fading, and then occur elsewhere, i.e., an up-and-down, recurring manifestation. In terms of treatment, atopic dermatitis is mainly coated with medication, with topical application of furnace glycolic lotion 3-4 times during the day and a hormonal ointment, such as Fu Yan Ning or Eloson ointment, at night. The treatment of urticaria is more focused on oral antihistamines, a generation of paracetamol, cyproheptadine, second-generation cetirizine, loratadine, imipramine, etc., choose one of each, take second-generation antihistamines during the day and a piece of first-generation antihistamines at night, adhere to a week, basically cured. If the effect is not good, you can add compound glycopyrrolate tablets, 3 times a day, 2 capsules once, for 10-15 days. For patients with symptoms of infection, such as fever, chills, diarrhea, etc., or a bright red rash, and conventional anti-allergy treatment is not effective, perfect blood routine + CRP test to get rid of infection triggers. Both are essentially allergic diseases. During the treatment period, do not drink alcohol, do not eat spicy and stimulating food, and drink more water to help the allergens out of the body.
