    If it's in the mouth rinse your mouth several times a day for a week or so with warm salt water about a t/spoon of salt to a cup of water.If it's cold sore try and get the pus out first then put a dab of perfume/cologne on it for a couple days.it will sting but it will dry it out and it will scab over and heal.

    That can sometimes be caused by a lack of a certain vitamin.

    Try taking a daily multivitamin.
