### Human:\ncan cold sores come back in only 1 spot all the time. i get a sore on my bottom lip about twice a year its always in the exact same spot. right in the center of my bottom lip. it starts as a lump inside the lip and the next day it works its way from the inside of my lip to the center on the outside. it takes a few weeks to get rid of it. i find that if i keep it dry and do not use lip balm then it goes away faster.\n\n### Assistant: that is the nature of this herpetic beast. it does come back often in the exact same spot or in close proximity. this characteristic often helps clinicians make the diagnosis.
