The blister rash of chickenpox is not to be picked. If you do, there is a risk that the herpes will not heal and there is a risk of local skin infection. The patient should only be treated with antiviral therapy and should pay attention to keeping the skin clean, and can use topical glycolic lotion for symptomatic treatment. The majority of patients will heal themselves within a week or so after treatment. The rash is self-limiting, if the patient is small and the clinical symptoms are mild, no special treatment is needed, only a little topical medication is needed. If the patient’s clinical symptoms are more severe, or there are complications, then you need to be hospitalized, and if you are hospitalized, you need to use antiviral drugs intravenously.
