Cold Sores, also referred to as fever blisters, are tiny lesions that are filled with clear fluid.
It is imperative to mention that cold sores are caused by viral agent a€“ Herpes Simplex virus (or HSV).
Itching and tingling sensations: Before the appearance of lesions the skin around the affected area becomes a little itchy with or without paresthesia or tingling sensation. Formation of blisters: Blisters are formed on the adjoining area where skin and lips fuses together.
Most people who get affected with herpes simplex virus do not experience any symptoms, but some may experience discomfort and pain during active infection. Once the body is infected by this virus, the person is vulnerable to develop recurrent episodes due to virus reactivation. Before any such viral reactivation event, the affected person usually predicts the exacerbation due to prodromal symptoms like feeling of itching and tingling sensation. Dona€™t share objects that are used on your body such as towels, glass, razor, lipsticks, etc. Make sure that you wash your hands after making a contact with your lesions otherwise it might spread to the rest of your body. The location in which the lesion forms.Laboratory testing can be performed but is not commonly used or needed. The appearance of a cold sore (fever blister) will gradually change as it progresses through the five stages of formation outlined below.
The timeline for this transformation (from first sign to complete healing) usually lasts between 8 and 12 days.
In most cases, a person's first indication that they have a cold sore starting to form is that they notice a new sensation (burning, stinging, itching, soreness, tautness, or swelling) in the area where the lesion will ultimately appear. What to look for - The area may become reddened, and slightly raised or elevated (papule formation). The first readily visible sign of cold sore formation is the appearance of multiple fluid-filled blisters. What to look for - The blisters are usually very tiny (smaller across than the thickness of a dime). Things to know - This is the stage where the total number herpes virions (virus particles, HSV) is the greatest. In about 25% of cases, the herpes infection is brought under control (either just by your body's immune system or with the help of antiviral medication) before blisters can develop. What to look for - Immediately after rupture, the lesion starts off as a shallow red ulcer (a wet, raw looking sore) whose surface then turns grey.
Things to know - This phase of fever blister formation can be the most painful stage, and the one during which it's most contagious. If the ulcer has formed in a location where it's not kept wet by moisture from the mouth, it will scab over.
During times when a scab has come off, you can see the amount of ulceration that still remains and the pink, newly formed tissue that surrounds it. Things to know - The formation of the scab is often accompanied by an itching or burning sensation. What to look for - A series of scabs will usually form on the lesion with each one flaking off before it's replaced by a new one.
Each new scab will be smaller than the previous one, until finally the lesion resolves fully and in most cases without scarring. Cold sores typically form in generally the same location as they have during previous outbreaks. Yes, during times when you have a cold sore spreading the herpes virus to others should be a concern. Cold sores, the liquids coming from them and even your own saliva can transfer virions to other people, or even other parts of your own body (see below). One common route by which the herpes virus is transmitted to other people is via direct skin-to-skin contact. It's best practice to refrain from being intimate with others or participating in contact activities (e.g. The difficulty associated with asymptomatic viral shedding in terms of prevention of transmission is that the infected person is unaware that the event is occurring. Virus particles can also be transmitted to others by way of intermediary objects that have touched your sore or saliva. Avoid sharing articles like an eating utensil, cup or glass, or items such as a razor, bar of soap, lipstick or lip balm applicator, toothbrush, or towel.Properly dispose of items used to apply medicines to or treat cold sores. Some people are at greater risk than others for complications associated with herpetic infections. Besides just oral infections, it's important to understand that the herpes virus can also cause infections in other body parts. A herpes infection of the eye can result in corneal blindness.If you wear disposable contact lenses and contamination is suspected, then throw them away.

As a cold sore continues to run its course, the number of virus particles present in it diminishes. Besides just when treating a sore, wash your hands (soap and water) repeatedly throughout the day. Dr Oz kicked off a brand new season on September 9 2013 with the stars of Whose Line Is It Anyway?

First, you may feel a tingling, itching, or burning sensation around your lips a few days before you notice a blister. It typically takes about 2 weeks for a cold sore to heal completely, but they usually go away on their own.

Viral infections are very common among Americans for they are readily transmitted by saliva and other bodily fluids. Cold sores, fever blister or medically termed as herpes labialis is a common viral infection caused by the reactivation of the latent herpes simplex virus in the nerves after primary herpes infection.
Cold sores can be mistaken as canker sores, another common oral condition, but both are very much different in their tendency to recur, in number and in duration. About 40 million Americans get cold sores each year with most of them experiencing one to three attacks annually.
After the primary infection by herpes simplex virus, the dormant virus can be reactivated in 20 to 30% of sufferers. Direct contact with cold sores can also spread the virus for the virus can enter through small breaks in the body. Most cold sores will heal by themselves within one week to ten days but if the condition is uncomfortable and unsightly, medications may be prescribed by your doctor. Your doctor will usually prescribe pencyclovir 1% cream or acyclovir 5% cream to apply in the early stages. Avoid sharing personal items that comes in contact with the mouth, for example toothbrush, with others. Avoid triggering factors that can reactivate the virus, for example applying sunscreen to cold sores areas before long exposure to sunlight, avoid trauma to lips and manage stress. Avoid rubbing your eyes or touching other parts of your body if in contact with cold sores. These are most frequently reported near the oral cavity (especially around the lips) and are usually found in group like lesions. There are two varieties of this virus; type 1 is responsible for causing fever blister whereas type 2 is mainly implicated as a causative agent for blisters on the genital areas. Moreover, the sores follows a predictable course with varying intensity of involvement in different individuals. When these blisters break, the clear inflammatory fluid of lesions form a crust before disappearing completely.
Initially this infection is followed by formation of tiny sores that are filled with fluid as discussed above.
Human body cannot completely overcome this virus which stays in the body in the state of dormancy. The overall size of the forming lesion generally correlates with the relative number of virions present.
And the inflammation reaction triggered by the presence of the virions and damage to skin cells they have caused is in full swing as it continues to clean up the carnage. This can include activities like kissing, or even just touching your sore against someone's face during a hug.
This is because the liquid contained in these blisters holds literally millions of herpes simplex virions. Usually by the time a scab has formed (the Crusting stage) the number of virus particles has lessened dramatically.

Cold sores are typically painful, red, and swollen, and can sometimes break open and leak a clear fluid. There are two types of herpes simplex virus, HSV-1 and HSV-2, and both can cause sores that appear on the mouth or genital area.

The herpesviruses are the most frequent cause of viral infection in the mouth and herpes simplex virus (usually type 1) is the one responsible for cold sores. They are usually fluid-filled blisters or sores found on the lips or around the mouth and are not an inherited condition. Early symptoms include pain, tingling or itching on the affected area a few days after exposure. Antivirals will only have maximum effect if given early in the disease but may be required for those with severe conditions, widespread or persistent sores, or those with weak immune systems.
Once these blisters or sores are burst, a crust like residue is usually formed which eventually heals within two-week time period.
Due to viral association, the cold sore can spread to uninfected normal individuals via close physical contact with the blister fluid. The symptomatology is highly variable, with some individuals showing no symptom at all while others experiencing mild illness.
These lesions are reddish or purplish in color and are most concentrated near the periphery of lips and mouth.
Young children are more vulnerable to spread this viral agent to other parts of their body due to immature immune system. In some individuals, the virus permanently stays there without showing any signs of its presence; while in other cases, it may show exacerbations. It's this inflammation response (a part of the normal healing process) that's responsible for redness, swelling and tenderness associated with cold sores as they continue through their stages. This includes people with either immature immune systems (newborn babies) or compromised ones (such as chemotherapy or HIV patients).

There are over-the-counter topical medications and prescription medications than can speed the healing process. Most people contract the herpes simplex virus for the first time during their childhood which will remain in the nerves till it gets reactivated. Treatment is meant to reduce the duration of cold sores and decrease the pain and uncomfortable symptoms. In most cases, signs of initial outbreak of lesions becomes evident within 3 weeks of viral exposure. The frequency of recurrent cold sore is 4-5 times in a year and each episode usually lasts for 4-10 days. Cold sores can easily be spread by close personal contact, like sharing a drink, kissing, or oral sex. If you frequently get cold sores, it may be worth talking to a medical professional about your options for treatment.
Blisters form after an hour or two, usually in clusters, at the junction of the lips but can extend to neighboring skin.
Most people report the recurrence of these lesions with moderate exposure to stress or in the setting of weak immune system. In some cases, associated symptoms like fever, moderate headache, general body aches, muscle aches, sore throat and swollen neck glands are also reported. It detected asymptomatic oral shedding on 12% of days, with an average duration of 24 hours for each episode.
