If the blister is oozing after breaking, you can use a dry cotton swab to absorb it and then apply ointment, the amount of ointment applied should be small and not too much. Generally, a sesame seed-sized ointment can be applied to a skin area the size of a dollar coin, and the scab should not be touched with water before it falls off. Do not touch the affected area with water before the scab falls off on its own. Change your underwear daily. Do not apply band-aids to avoid secondary infection from wet wounds. Determine if the wound is infected: If the wound persists without crusting, oozes purulent discharge, and has ulcer formation, it may be infected, so please contact your primary care physician.
