What Are The Symptoms Of A Cold Sore

Common Food Allergies: Does Gluten Cause Canker Sores?

It is essential to define a fever blister. Understanding the symptoms enables you to identify the issue and separate it from skin conditions that are similar to cold sores.

The initial symptom of an outbreak usually involves a slight tingle or even burning sensation on the lip. This will be confined to a single area. This location is typically where the virus entered your body.

Following the tingle stage, a small cluster of blisters will appear. These blisters will typically increase in size and contain fluid. After a short time, the blisters will burst, and a scab will form.

Once the scab has naturally flaked away, new skin will emerge. At this time the outbreak is considered to be over and the virus no longer contagious. The typical outbreak will last no longer than two weeks, with proper OTC cold sore treatment.

During your initial cold sore outbreak, which is often the most problematic and painful, additional symptoms can also occur. These symptoms include, but are not limited to, fever, headache, mouth pain, and swollen lymph nodes.

To Summarize:

  • Understanding the symptoms and lifecycle of cold sores is critical. This can not only help you to understand HSV-1 and address other ailments. If you find yourself with a blister, yet cold sore symptoms are not occurring, you can likely conclude something else is to blame.

What Causes Cold Sores

When we ask what causes cold sores in the mouth and on the lips?, we really should be asking ‘what triggers cold sores?’. The herpes simplex virus is the initial cause of the infection without it there are no cold sores or blisters but the blisters themselves are often triggered by psychological and environmental factors, such as stress or a coldi.

Triggers of cold sore outbreaks vary from person to person. What causes cold sores to appear for one person may not be the same for another. It’s important to figure out your likeliest cold sore triggers so you can avoid them, or at least manage symptoms more quickly and effectively when they occur.

How To Avoid Transmitting Hsv

If you have a cold sore, be sure to wash your hands after touching it and be especially careful to avoid touching your own eyes after touching your cold sore. It is the fluid contained in the blisters that is considered to be the most infectious. While you have a cold sore it is also important to avoid:

  • sharing toothbrushes
  • sharing drinking glasses or bottles
  • sharing cutlery
  • sharing towels or other personal items
  • close contact with newborn and young babies
  • kissing others
  • close contact with children with burns or eczema
  • close contact with people with suppressed immune systems.

How Is Herpes Simplex Virus Transmitted

In order to cause an infection, the herpes simplex virus has to enter into the body through small breaks in the skin or through a mucous membrane such as the inside of the mouth or the genital or anal skin.

HSV-1 is highly contagious. It can be spread through saliva, skin-to-skin contact, or by touching an object handled by someone infected with the virus. HSV-2 infection mainly occurs through sexual contact. In rare circumstances, HSV-1 and HSV-2 can be passed from mother to child during childbirth causing neonatal herpes.

Although transmission is most likely when the infected person has an active sore, the virus can also be passed on even if the infected person is asymptomatic.

Unfortunately, if you have been infected with the herpes simplex virus , the virus will remain dormant in your body forever. From time to time in periods of stress, it can reactivate, triggering cold sores. Doctors believe that people experience recurring cold sores due to a genetic mutation affecting the immune system. Most people will only experience a few cold sore flare ups in their lifetime.

Treatment For Cold Sores

Cold sores are generally not dangerous and do not cause any permanent damage to the skin. Treatment does not cure the infection and is not necessary for most cases. Avoid picking the scab or breaking blisters as this can cause secondary infection with bacteria, or scarring. Creams to treat the symptoms can be soothing, as can ice on the blisters. Simple painkillers may occasionally be required. Povidone-iodine ointments can be dabbed onto the cold sores and may reduce symptoms in some people.Antiviral medications come in many forms, including creams and tablets. Medications such as aciclovir and famciclovir shorten the duration of the cold sore by reducing the ability of the virus to reproduce. Aciclovir cream works best when applied to the blister at the earliest stages of cold sore development, when the area is tingling. However, not everyone experiences warning signs of an impending cold sore.

What Are The Symptoms

The first symptoms of cold sores may include a spot that tingles, burns, or itches around your mouth and on your lips. You may also have a fever, a sore throat, or swollen glands in your neck or other parts of the body. Small children sometimes drool before cold sores appear. After the blisters appear, the cold sores usually break open, leak a clear fluid, and then crust over and disappear after several days to 2 weeks. For some people, cold sores can be very painful.

Get To Know Cold Sore Triggers

Due to their potentially embarrassing nature, many people look to get rid of cold sores overnight.

However, preventing a cold sore is quicker and safer approach than treating an outbreak. People can try to avoid triggers that cause cold sores, keeping the sores on their skin from appearing in the first place.

Preventing a cold sore may also help reduce the risk of spreading the virus to other people.

Not all cold sores can be prevented, but knowing what triggers them is an important step in cold sore management. Common cold sore triggers include:

  • certain foods
  • hormonal changes, especially from menstruation or taking birth control pills
  • a weakened immune system

Keeping a diary or log may help a person work out what triggers their cold sores. Writing down things, such as diet, activities, illnesses, and life events can help narrow down what has preceded the outbreak.

An added benefit of knowing cold sore triggers is the ability to be even more proactive in taking medications. Consequently, if a person knows they were exposed to a cold sore trigger, they can be especially watchful for early signs and get started on medications right away, if needed.

Ruling Out Conditions That Resemble Oral Herpes

Canker Sores

Simple canker sores are often confused with the cold sores of HSV-1. Canker sores frequently crop up singly or in groups on the inside of the mouth, or on or underneath the tongue. Their cause is unknown, and they are common in perfectly healthy people. They are usually white or grayish crater-like ulcers with a sharp edge and a red rim. They usually heal within 2 weeks without treatment.

This aphthous ulcer is located in front of and just below the bottom teeth.


Oral candidiasis is a yeast infection that causes a whitish overgrowth in the mouth. It is most common in infants, but can appear in people of all ages, particularly people taking antibiotics or those with impaired immune systems.

Other conditions that may be confused with oral herpes include herpangina , sore throat caused by strep or other bacteria, and infectious mononucleosis.

What Typically Triggers Cold Sore Outbreaks

If you were diagnosed with the herpes simplex virus, especially type 1 , cold sore outbreaks may be common. While the virus may remain dormant during certain periods, when its triggered, you can expect to see cold sores.

While some people believe that food can trigger cold sore outbreaks, environmental factors are more likely to trigger an outbreak than anything else.

Exposure to hot sun, cold wind, a cold, or other illness is usually the cause of an unexpected cold sore outbreak. Fluctuating hormones might also be to blame.

  • Emotional or physical stress Stress can lead to a weakened immune system, triggering a cold sore outbreak.
  • Fatigue Exhaustion or feeling run down can allow the cold sore virus to reactivate.
  • Illnesses such as , a cold or a chest infection
  • Surgery or injuries to the skin
  • Over-exposure to sunlight UV radiation from the sun may suppress the immune system and give the cold sore virus an opportunity to reactivate.
  • Exposure to strong winds
  • Hormonal changes from periods or birth control pills
  • Consumption of certain foods and/or alcohol

How Hsv Is Transmitted

The herpes simplex virus spreads between people, usually through contact with saliva or direct contact with a blister. The most infectious time is in the first few days when the blister is forming. Sometimes, people can pass the virus to others when they have no symptoms. This is because the virus may be lying dormant in the skin cells of the lips.

What Is The Difference Between Celiac Mouth Sores And Cold Sores

It is common to develop mouth sores if you have gastrointestinal issues when the ailment is severe and prolonged. When it comes to the direct topic of celiac disease, most mouth sores associated with this disease are canker soresnot cold sores.

Canker sores are simple nodules of tissue that develop when your mouth becomes irritated. These sores form on the inside of your mouth. Most notable within the lining of your cheeks. While certain foods, gum chewing, and dental procedures can cause canker sores, illness can promote them as well. This is why canker sores are relatively common in those who suffer from celiac disease.

Cold sores, on the other hand, are born of the herpes virus and have nothing to do with any other condition. While celiac disease could trigger a cold sore outbreak if you carry HSV-1, you will not get a cold sore from celiac disease as the two have no connection.

Herpes And Newborn Infants

Cold Sores vs Canker Sores

Herpes infection in a newborn can cause a range of symptoms, including skin rash, fevers, mouth sores, and eye infections. If left untreated, neonatal herpes is a very serious and even life-threatening condition. Neonatal herpes can spread to the brain and central nervous system, causing encephalitis and meningitis. It also can lead to intellectual disability, cerebral palsy, and death. Herpes can also spread to internal organs, such as the liver and lungs.

Infants infected with herpes are treated with acyclovir, an antiviral drug. They usually receive several weeks of intravenous acyclovir treatment, often followed by several months of oral acyclovir. It is important to treat babies quickly, before the infection spreads to the brain and other organs.

Can Cold Sores Be Prevented

If you have never had a cold sore, avoid skin-to-skin contact with someone who has an active cold sore. If you have had a cold sore, you may prevent or reduce the number of recurrences by determining what triggers your outbreaks and avoiding the trigger. For instance, if sun exposure is a trigger, use sun screen when in the sun. If you have frequent outbreaks, consult with your health care provider. Starting treatment as soon as you know you are developing a cold sore can promote healing and reduce the time it takes a cold sore to heal.

Upping Your Intake Of Lysine

Older laboratory of studies performed in vitro showed that lysine an essential amino acid that you get from food may be able to help prevent cold sores. Lysine is also available as an oral supplement and as a cream.

Lysine is thought to prevent against cold sore outbreaks because it reduces the activity of arginine, an amino acid needed by the herpes simplex virus to replicate.

The richest sources of lysine are foods that are high in protein, such as:

  • meat, specifically beef, chicken, and pork
  • cheese, especially parmesan
  • fish, particularly cod and sardines
  • soybeans

Is Celiac Disease A Cold Sore Trigger

Allergies and Sore Throat Treating the Cause

While the answer is not a definitive yes it is mighty hard to think celiac disease would have no consequence at all. Unlike gluten sensitivity, celiac disease is a severe autoimmune issue where the body begins to attack itself. This type of alarming disease would naturally leave the body open to attack by a host of internal and external forces causing variety of extraintestinal manifestations.

If you are familiar with the basic cold sore triggers, you know that illness and stress are common triggers. So are dietary concerns. When discussing the topic of celiac disease, all three of these issues are at the forefront.

  • Gluten: Dietary concern that can act as a trigger.
  • Stress: The worry and general concern over your celiac diagnosis.
  • Illness: As your small intestine continues to come under fire, your body is taxed and worn down. This alone can weaken your system enough to allow HSV-1 to become active.

There Is More Than One Type Of Herpes Infection

There are two types of herpes simplex infection: herpes simplex virus type 1 and herpes simplex virus type 2 . Cold sores around the mouth are generally caused by HSV-1. Most cases of genital herpes are caused by HSV-2. Cold sores on the mouth can cause genital infection during oral sex for people who do not already carry the cold sore virus. There are many other viruses that are also in the herpes virus family, however the infection and symptoms are different. One example is varicella zoster virus which causes chickenpox and shingles.
