Allergic back bumps are considered to be a case of atopic dermatitis, which in addition to small bumps can also have such polymorphic rashes as papules, blisters, and flaky erythema, accompanied by intense itching. In clinical treatment, if the rash is densely distributed, fused into patches, and there are large scratches and blood scabs, it is necessary to immediately administer compound glycyrrhizin injection 0.12 g/time, 1 time/day. If no relief is seen after application, immediate intramuscular injection of compound betamethasone injection 1x/day, 1x/time is needed for anti-inflammatory and immunosuppressive treatment. In the choice of topical medication can be applied mometasone furoate ointment 1 time/day and with fluphenazole butyl ointment 2 times/day for treatment.
