TREATMENT
The area should be cleansed with mild soap and a protective dressing applied. Unless a blister is painful or interferes with function because of its size, it should not be punctured. If puncturing is required, it should be done aseptically, with the skin left in place. A sterile pressure bandage should then be applied.
