Herpes labialis is a common infection caused by the herpes simplex virus. The most common symptom of the infection is a cold sore.
Usually, the herpes simplex virus, type 1 is responsible for the herpes labialis infection. However, the infection can be caused by herpes simplex virus, type 2. Type 2 infections are rarely a cause of this condition, but there are instances when it happens.
Cold sores are small, painful blisters usually appearing on the lips, mouth, gums or on the face around the mouth. They are also known as fever blisters, oral herpes and canker sores. Initially following infection, the cold sore symptom appears within one to two weeks.
As the saying goes, the exception makes the rule, and that applies in this instance. In other words, there are exceptions to the one-to-two-week rule. The first bump may not appear until three weeks or more have passed. These lesions or blisters run their course in about seven to ten days. Again, the amount of time varies and outbreaks can last longer than two weeks.
The herpes simplex virus may become latent after the initial occurrence. The virus can remain unnoticed in the nerve cells for an indeterminate amount of time before becoming active again and causing a breakout in the same area that it affected originally.
As the saying goes, everything is easier the second time around. This is normally the case with this infection. Recurrence will probably be milder and may be triggered by sun exposure, illness, stress or other causes. Some accompanying symptoms may include itching, burning, sensitivity and a tingling sensation experienced a couple days before blisters appear.
The herpes labialis infection can be uncomfortable to painful and occurrences can also vary significantly. Now that you know a little more about the condition, you should know that there are ways to make the condition more bearable. Research online or at a library, or ask your doctor for information.
