Oral herpes causes an outbreak of small red sores on the skin. While these blisters typically develop on the lips, they can also surface on the nose, hands, chin, or mouth. The sores usually have fluid in them, and they can be quite irritating and painful. Cold sores go away in about one to two weeks.
Oral herpes has 2 forms: acute or primary and recurrent or chronic. The acute form usually occurs in childhood and is associated with rapid onset of sores or ulcers in the mouth. This stage last for 1-3 weeks and can be treated with anti-viral medications. The sores heal without scarring. The recurrent form occurs only on the sun-exposed portion of the lower lip where the skin meets the lip. If treated when the lip begins to burn, the blister or vesicle stage can be avoided and the usual 2 week period from onset to healing can be shortened. Again, healing occurs without scarring.
