To cure a sting, begin by scraping the sting off the skin’s surface using the edge of a credit or debit card. Warm water and soap were used to clean the area. You may also use and retrieve an icepack at 10-minute intervals for an hour, or you could take a pain reliever or antihistamine to lessen the pain or swelling. Another method for treating a sting is to apply a soaked cotton ball of apple cider vinegar or lemon juice to the sting or to put a slice of lemon to the sting.
