Triggers For Cold Sores
In some people the HSV infection causes cold sores, which erupt following a trigger event such as a cold. This explains the term cold sore. Other triggers that may cause an attack of cold sores include:
- feverish illnesses, like influenza, or chest infections
- hormonal changes, such as the menstrual period
- emotional or physical stress.
It is important to remember that cold sores are a symptom of ongoing infection rather than a new infection. The sores usually recur in the same place.
How Do You Get Cold Sores
Cold sores are generally contracted from skin to skin contact with an infected area. For example, if someone has a cold sore on their lip they can pass on the virus to another persons mouth through kissing.
The usual incubation period of the virus is approximately two to twelve days after the first exposure to the virus. As most people contract cold sores before the age of seven, it is common for a person not to remember their first or primary cold sore outbreak.
Once infected with cold sores, the virus remains inside the body in a latent state. Throughout a persons life the virus can then become activated causing a cold sore recurrence.
When To See A Dermatologist Or Doctor About A Cold Sore
Aside from preventing scarring, there are times when youll want to see a doctor or dermatologist, right away to prevent further complications.
If for instance someone has eczema, there can be a bad outcome if the eczema patches get infected by the herpes , Li said, adding that people with eczema who experience cold sores should visit a dermatologist right away.

Cold sores are caused by a variety of physical and mental triggers, including:
- Exposure to inclement weather or direct sunlight

So Cold Sores Are Only Caused By Hsv
Both HSV-1 and HSV-2 can cause cold sores on the mouth and face.
Although its more common for HSV-1 to cause cold sores, it isnt impossible for HSV-2 to cause them, too.
Cold sores arent the same thing as canker sores or mouth ulcers. They each have different causes and two entirely different presentations.
Cold sores:
- are caused by the herpes simplex virus
- usually develop near the outside of the mouth, such as below your nostrils or on your lips
- cause redness and fluid-filled blisters
- usually appear in groups
- eventually break and ooze, forming a crust-like scab
- may take 2 to 4 weeks to completely heal
Canker sores:
- may be caused by food or chemical sensitivities, dietary deficiencies, minor injury, or stress
- may develop anywhere inside your mouth, such as at the base of your gum line, inside your lip, or under your tongue
- are shaped like a circle or oval
- are typically yellow or white with a red border
- may appear solo or in groups
- usually take 1 to 2 weeks to completely heal
HSV-1 is spread through direct contact with the virus, which can be present in or around cold sores, in oral secretions , and in genital secretions .
Some of the ways it can be transmitted include:
- kissing someone on the mouth
- sharing eating utensils or cups
- sharing lip balm
- performing oral sex
The herpes virus usually affects the area where it first made contact with the body.
Some of the ways HSV-2 can be transmitted include:
The Difference Between Canker Sores & Cold Sores
Cold sores or fever blisters are caused by the herpes simplex virus and are usually relatively easy to identify. To view pictures of the herpes virus visit our Herpes Pictures page.
There is another condition which can cause ulcers inside the mouth known as Canker sores. Canker sores are not a form of herpes, however, they are often confused and mistaken for cold sores.
Canker sores are ulcerations, especially of the lip or oral mucosa and can be caused by acute stress, trauma to the area in your mouth, allergies, or by a reaction to a particular bacteria.
Canker sores are not considered to be contagious. Cold sores and mouth herpes on the other hand are caused by the herpes simplex virus and can be very contagious.
If you are experiencing ulcerations on or inside of your mouth please visit your health care provider for a professional diagnosis. These two conditions can appear very similar and should not be self-diagnosed.

Red or swollen gums, swollen glands in the neck, fever, and muscle aches are all possible symptoms.
Why Do Some Cold Sores Come Out Of Nowhere
Heres the weird thing about cold sores: You can be infected with HSV-1 or HSV-2 and not have visible symptoms for years. In fact, some people can have several cold sores a year or only one or two in their lifetimeit really just depends on your body.
Ive had a lot of patients who wonder if their partner cheated on them because they suddenly developed a cold sore, Dr. Rodney says. But thats not the casethey just had their first visible outbreak later in life.
Thats because the virus lies dormant in your skins nerve cells, only to rear its head when its triggered to do so. These recurrences can be set off by a slew of different things, like a viral infection or fever, hormonal changes, stress, fatigue, exposure to sunlight and wind, changes in your immune system, or a skin injury, the Mayo Clinic says.

Causes And Symptoms Of Fever Blisters And Cold Sores
Now, before you get fixated on the word “herpes,” you need to know that oral herpes is not the same as genital herpes . While both are contagious, your cold sores and fever blisters will usually show themselves in or around the mouth.
When a person first contracts the virus , the initial breakout will occur in a few days, and can be accompanied by a fever, sore throat, aches and pains, and a headache. Unfortunately, when youre feeling better after your first outbreak, the fun isnt over. The virus doesn’t leave your body: it simply remains dormant in your nerve cells. This means you can have reoccurrences throughout your life, because there’s no cure for HSV-1.
Fortunately, the reoccurrences won’t likely be as bad as the first one. The next cold sore will likely start off with a prickly or tingling and itchy feeling, small bumps in and around your mouth, and quickly turn into “fluid-filled blisters that rupture after a day or two.“
Following the burst of the blister, the fluid will ooze out, sometimes turning into a crusty covering and forming a scab over the open wound, which is tender to the touch, and can crack open. An outbreak, from the first initial tingle to the scab falling off, typically lasts from seven to 10 days.

-
The brain or the spinal cord The virus can cause serious inflammation known as meningitis or encephalitis, which is particularly deadly in those with weaker immune systems.
How Do You Know Its A Cold Sore
An initial redness, swelling, or itching usually first develops in the area where the infection will erupt. It leads to painful and fluid-filled blisters, usually on your lips, and these blisters leak fluid and become sores. After a couple of days, the sores will begin to crust over and heal. Cold sores usually heal, leaving you without a scar as long as you dont pick at it, of course.
