Chickenpox blistering symptoms after 1-2 days after the beginning of the scab, 1 week or so can fall off naturally, and usually does not leave a scar. Chickenpox is edematous degeneration of the cells of the acanthocyte layer, and the lesions are superficial to form blisters, which appear almost at the same time as the fever, with a red maculopapular rash appearing on the first day of the fever, and then turning into a blister within 24 hours, with the fluid in the blisters initially clear, and then gradually cloudy, crusting, and peeling off in about 7 days. However, it should be noted that after the old rash is crusted over, the new rash will still keep appearing in batches, so the patient may have red maculopapular rash, light herpes and turbid herpes and crusted rash at the same time. If the skin is scratched due to itching during the blistering period, and a purulent infection occurs, it may lead to prolonged scab removal or even scarring. In addition, during the chickenpox attack and scabbing period, you should avoid bathing to prevent infection, and eat less spicy and greasy food to avoid affecting the improvement of skin lesions. Pay attention to isolation, to avoid infecting others, used items are recommended to be washed in time, and disinfected by sunlight.
