How does red itch do after sticking 3 volts to stick

If the skin is red and itchy after applying the Sanfu patch, it is recommended to remove the Sanfu patch as soon as possible, and it is best not to apply the Sanfu patch in the future. In the local skin redness, you can choose to apply a weak hormone ointment to the affected area. If the erosion exudates, you need to use boric acid solution wet compress. After the exudation is completely relieved, the local rash is dried, and then topical hormone ointment is applied to the affected area. If the patient's itching is obvious and topical medication alone does not relieve it, oral antihistamines can be used to relieve itching symptoms.
