How to Get Rid of a Cold Sore

Dealing with a cold sore can be both painful and unsightly. Knowing how to get rid of one quickly can significantly alleviate discomfort and help you maintain your daily activities. In this article, we will explore some practical and fast-acting solutions for treating cold sores.

It’s crucial to remember that early treatment is key in reducing the duration and severity of a cold sore outbreak. So, when you notice the initial tingling or itching sensation, take swift action and use the methods discussed in this article to minimize the impact on your daily life.

What Is a Cold Sore?

Cold sores are typically caused by the herpes simplex virus (HSV), usually HSV-1, but sometimes HSV-2. This virus can be spread through close personal contact, such as kissing, sharing of personal items, or oral sex.

Once infected, the virus remains in your body, though it may lie dormant. Your immune system significantly influences the occurrence of the sores. They are more likely to occur if your immune system is weak.

Itching or Burning Feeling

When a cold sore is about to erupt, you’ll often experience an uncomfortable itching or burning sensation in the affected area. This is an early warning sign that the infection is becoming active.

The itch can be mild or intense. Either way, it’s a clear indicator that a cold sore is on the horizon.

Appearance of Blisters

As the cold sore progresses, you’ll notice the formation of small, fluid-filled blisters. These blisters are typically clustered together and can be quite painful.

Over the next few days, they may enlarge and eventually burst, leading to the release of infectious fluid. This stage is a critical part of the cold sore’s life cycle.

Highly Infectious

Cold sores are highly contagious. They can be transmitted through direct contact with the cold sore itself or with the fluid it contains. Even when the cold sore has crusted over, indicating that healing has started, the virus can still be active and contagious.

Avoid close contact with others, especially kissing, during an outbreak to prevent spreading the virus. Proper hygiene and caution are essential to reduce transmission.

Healing Period

In the initial stages, you might observe a tingling sensation or small, blister-type sores near the mouth or on your lips. Don’t panic, as your body’s immune system will start combating the virus immediately.

Over the next 7 to 10 days, these blisters will dry out and begin to crust over, forming a scab.

Depending on your immune system’s strength, your body will work diligently to heal the sores. By encouraging a strong immune response, eating well, and getting plenty of sleep, you can speed up this process.

Cold Sore vs. Canker Sore

A cold sore, which you might feel as a tingling sensation on your lip, is a cluster of blisters caused by the herpes simplex virus. It’s contagious and appears outside your mouth, often resulting in a scab once the blister bursts.

In contrast, a canker sore is a small ulcer inside your mouth, typically on the soft tissues or at the base of your gums. Non-contagious and often triggered by stress or injury, you’ll notice a painful, round, white, or yellowish sore that isn’t accompanied by a blister.

Factors Influencing Cold Sores

Injury and Trauma

When you injure yourself or experience trauma, it can weaken the local immune defenses of your lip tissue, making it more susceptible to the activation of the herpes simplex virus (HSV).

Additionally, any cuts or breaks in the skin can serve as entry points for the virus, increasing the likelihood of developing a cold sore. Even just a minor lip bite inside your mouth can cause a flare-up.

Contact with an Infected Person

Coming into direct contact with a person who has an active cold sore can significantly increase your chance of contracting the virus yourself. This is due to the highly contagious nature of the herpes simplex virus.

If you touch a cold sore on an infected person and then touch your own mouth or an area of broken skin, you may inadvertently introduce the virus to your body, potentially leading to a cold sore outbreak.

Poor Hygiene

Maintaining poor hygiene habits can increase your likelihood of developing cold sores. If you neglect proper handwashing, especially after coming into contact with someone who has cold sores, you can easily transfer the herpes simplex virus into your body.

Additionally, not keeping your face and mouth area clean can create an environment that the virus finds favorable for infection and replication.

Sharing of Personal Items

Sharing personal items such as lip balms, utensils, towels, or any object that might come into contact with the mouth is a common way to spread the herpes simplex virus. Even if an individual doesn’t currently have an active cold sore, the virus can be present on their belongings.

By using these shared items, you risk introducing the virus directly to your mouth, which could result in a cold sore outbreak.

Multiple Partners

Engaging in intimate activities with multiple partners increases your exposure to different strains of the herpes simplex virus, the cause of cold sores. Each partner may carry the virus even if they do not have visible symptoms, and close contact can lead to the transmission of HSV.

The more partners you have, the greater the chance you’ll come into contact with someone who is a carrier of the virus, thus increasing your risk of contracting it. Practicing safe habits can help reduce the potential for spreading or contracting HSV.

Stress and Fatigue

When your body is under stress or fatigued, your body is less effective at controlling the herpes simplex virus. Stress, both emotional and physical, can lead to hormonal changes and trigger the virus’s reactivation.

High-stress periods, inadequate sleep, and exhaustion often act as catalysts, causing cold sores to erupt. 

Changes in the Hormone Levels

Hormonal fluctuations, especially in women, can play a significant role in cold sore development.

Hormonal changes during menstruation, pregnancy, or menopause can weaken the body’s defenses against the herpes simplex virus.

Weak Immune System

A weakened immune system is one of the primary factors that facilitate cold sore formation. Your immune system is responsible for keeping the herpes simplex virus in check, preventing it from causing outbreaks.

When your immune system is compromised the virus can become more active, leading to cold sores.

Home Remedies for Cold Sores

There is a range of effective home remedies that can help soothe the pain, reduce the duration of cold sores, and enhance your comfort during an outbreak.

Cold Compress

A cold compress helps mitigate cold sores by reducing inflammation and providing relief from pain and discomfort. It can significantly limit the swelling and redness and accelerate the healing process.

The application of the compress works to slow down blood flow to the infected area. This not only numbs the area, providing immediate relief from painful symptoms but also helps to restrict the virus’s ability to spread further, promoting faster recovery.

Apple Cider Vinegar

You can try applying apple cider vinegar (ACV) to the cold sore with a cotton ball.

The acidic properties of ACV may help to reduce the virus, reduce inflammation, and speed up the healing process.

Essential Oils

Tea tree oil and peppermint oil are two popular essential oils for cold sore treatment. Dilute a few drops of either oil with a carrier oil, such as coconut oil, and gently dab it onto the sore.

These oils have antiviral properties, which may help to reduce the severity of the outbreak.


Kanuka honey, a close relative to manuka honey, is well-known for its antimicrobial properties.

To use it as a cold sore remedy, apply a thin layer of kanuka honey directly onto the sore several times a day.


Propolis, a natural resin produced by bees, has been found to have antiviral effects.

It can be purchased in a concentrated form like a tincture or ointment and applied directly to the cold sore to help reduce its duration and severity.

Lemon Balm

Lemon balm is reputed to have antiviral properties, making it a popular choice for treating cold sores.

Apply lemon balm cream or ointment to the affected area several times a day to help soothe the sore and potentially shorten its duration.


Lysine is an essential amino acid that may help to prevent cold sore outbreaks. It’s available as an over-the-counter supplement and in some foods like fish, chicken, and dairy products.

Incorporating lysine into your diet might aid in reducing the frequency of cold sores, although more research is needed to confirm its effectiveness.

Vitamin C

Vitamin C plays a crucial role in boosting your immune system, which helps your body fight against infections, including that of the herpes simplex virus causing cold sores. 

Consuming vitamin C-rich foods or taking supplements promotes wound healing and tissue repair, hastening the healing process of the sores. 

Moreover, as an antioxidant, vitamin C combats the damage caused by free radicals, potentially decreasing the severity and duration of a cold sore outbreak. 

Your body can’t produce vitamin C, so getting enough from your diet or supplements is essential to keep cold sores at bay.

Aloe Vera

Applying aloe vera to cold sores can provide you with some relief. Aloe Vera, which is known for its anti-inflammatory and healing properties, soothes pain and reduces redness associated with cold sores. 

The natural compounds in aloe vera can expedite healing and prevent the sores from spreading. Further, aloe vera has antiviral properties that help neutralize the herpes virus, reducing the frequency of future outbreaks. 

Its moisturizing effect also keeps the skin around the sore soft and prevents it from cracking and bleeding, promoting a faster healing process.

Stress Management

Stress can weaken your immune system, making you more susceptible to cold sores. You can manage stress by engaging in calming activities like meditation, reading, or taking a relaxing bath.

This can boost your immunity and subsequently reduce the frequency of cold sore outbreaks.

Regular Exercise and Activity

Regular exercise and staying active keep you fit and improve your body’s ability to fight off infections.

When you engage in activities like jogging, yoga, or even household chores, it enhances blood circulation in your body, and this helps to strengthen your immune system.

Medical Treatment for Cold Sores

Over-the-Counter Medications

Cold sores can be effectively treated using over-the-counter (OTC) medications. Topical creams can be applied directly on the sore to speed up healing. Additionally, OTC patches can shield the sores while they heal.

For pain and inflammation, non-prescription anti-inflammatory drugs offer relief. Applying a lip balm or cream can also keep your lips moist and prevent the sore from cracking, further reducing irritation.

Antiviral Medications

Antiviral medications help manage cold sores by inhibiting the replication of the herpes simplex virus responsible for causing them. Upon application, these drugs enter the virus-infected cells and block the viral enzymes, thus preventing the virus from multiplying and spreading further.

These medications reduce the severity and duration of cold sores. They are most effective when taken at the earliest sign of an outbreak. Frequent use can also lower the recurrence rate of cold sores, thus providing an effective management solution.

Numbing Creams

Topical anesthetic creams can provide relief from discomfort. Local anesthetics are available as a cream, gel, or spray and are effective for numbing the area temporarily. Remember to use a cotton-tipped swab to apply medications to avoid spreading the cold sore.

It is essential to begin treatment as early as possible for the best results. Consult your healthcare provider if you need clarification on which treatment is best for you.

When to See a Doctor

Cold sores are contagious and often heal on their own within 2-4 weeks. However, it’s important to know when to see a doctor.

Does Not Heal or Gets Worse

If your cold sore doesn’t improve within a few weeks or if it’s causing you significant discomfort, it’s time to visit a doctor.

Over-the-counter pain relievers may help ease the pain and discomfort of a cold sore. However, if pain persists or becomes more severe, consult your doctor for further advice.

Repeat Occurrence

Frequent outbreaks can be symptomatic of an underlying illness, which, if left untreated, might result in more severe problems. If in doubt, see a medical professional. 

Medical professionals, specifically those who have expertise in dealing with infectious diseases, can provide expert advice and treatment. They possess the ability to prescribe potent antiviral medications that can help alleviate the distressing symptoms and, importantly, lower the frequency of these recurrent outbreaks.

When It Involves the Eyes

If symptoms appear near your eye or cause eye irritation, it can be a sign of a more serious infection. Seek immediate medical attention to prevent potential damage to your vision.

Remember, while cold sores are common and usually heal on their own, it’s essential to listen to your body and seek medical advice when necessary.

How to Prevent Cold Sores

Personal Hygiene

Engaging in good personal hygiene practices consistently is an effective way to lower your susceptibility to cold sores. This mainly revolves around cleanliness, notably maintaining clean hands to stop virus transmission. 

Touching a cold sore and a different body part later, susceptible areas such as your eyes and genitals increase the chances of spread. Further, it’s crucial to understand that the herpes simplex virus, responsible for cold sores, thrives in unhygienic conditions. 

Prioritize your personal cleanliness to create an environment where these sores find it challenging to proliferate, hence protecting your health.

Drink More

Sufficient hydration is key in the prevention of cold sores. An adequately hydrated body enhances overall body function, including the immune system’s ability to combat the herpes simplex virus, which causes these sores. Ensure you regularly consume water to keep your body functioning optimally.

Moreover, a dehydrated body often triggers the activation of the herpes simplex virus, leading to cold sores. So it’s not just about drinking water but doing so in adequate and regular portions that keep your body functioning optimally.

Practice Caution

Prudence in avoiding cold sores involves observing certain precautions, specifically around people with active cold sores. 

For instance, it’s recommended to avoid close contact with sufferers until their cold sore heals entirely. This effectively minimizes your risk of contracting the virus.

Reduce Stress

Effectively managing your stress levels can significantly contribute to averting a cold sore outbreak. Often, heightened stress triggers the activation of the virus, resulting in cold sores. Regularly checking what triggers your stress and implementing effective coping mechanisms are crucial steps.

This could include engaging in regular exercise, practicing mindfulness or meditation, or even seeking assistance from stress management experts. When your mind is at peace, your body can focus more on combating viruses, thereby reducing the probability of a cold sore outbreak.

Avoid Alcohol

When you consume alcohol, it can weaken your immune system, making you susceptible to infections, including cold sores. Dehydration, another side-effect of alcohol, can also prompt the herpes virus.

So, avoid alcohol to boost your immunity and maintain proper hydration to prevent cold sores.

Eat a Balanced Diet

Eating a balanced diet rich in vitamins, healthy fats, and antioxidants can strengthen your immune system. A robust immune system can effectively suppress the herpes virus.

To prevent cold sores, consume fruits, vegetables, lean proteins, and whole grains, which are essential to a healthy immune system.

Don’t Share Personal Items

Sharing personal items like utensils, lip products, or towels can unintentionally spread the herpes virus between people. 

Remember, the herpes simplex virus can live on these surfaces for a while, so the less you share, the lower your chances of coming into contact with the virus.

If you avoid sharing these items, you significantly reduce the risk of contracting the virus or passing it on to others, thus preventing the appearance of cold sores.
