Redness, swelling and the formation of a blister can be expected at the treatment site. An over-the-counter pain reliever can be used to control pain. Patients will be directed to wash the site daily while fluid continues to ooze from the wound, usually for five to 14 days, until a dry crust forms. The crust will eventually fall off by itself. Healing time for head and neck procedures is two to six weeks; longer for other parts of the body.
