What's the itch on the plaster?

Contact dermatitis refers to allergic reactions locally after the patient's skin contacts with some allergenic substances. Clinical manifestations include blisters, papules, erythema and itching. Allergic reactions normally occur within 12-8 hours of contact with allergenic substances. The severity of symptoms is mild or severe, and has a certain relationship with the patient's sensitivity to allergenic substances. Itching after sticking plaster has a certain relationship with personal constitution and drug ingredients. When the above situation occurs, it is necessary to remove the plaster in time and locally clean it. If necessary, some anti-allergic drugs should be used under the guidance of a doctor for treatment.
