There are a number of factors that could cause the eruption of blisters around the lips. Some of these factors, like environmental and weather changes are out of an individuals control. However, most other causes of the occurrence will have a certain amount of controllability by the affected individual.

If the condition is caused by the Herpes virus, some individuals may notice a spread of the blisters to areas of the nose, cheeks or even fingers. In some rare cases, the patient may also experience the development of some irritating and rather painful canker sores within the mouth. The virus can be easily transmitted from one individual to another by way of skin to skin contact, kissing or even the sharing of eating utensils. The virus therefore is very contagious. . Once you have contracted the virus, even after these blisters have been cured, the virus will continue to remain in your body in an inactive state. The virus would reappear only when your body is going through a significant amount of stress. Most of the blisters will clear up in about a week and reappear the next time your body is stressed.
