Cold sores are fluid-filled blisters commonly seen around the mouth or on the side of the lips (1). Caused by the Herpes Simplex Virus 1 (HSV-1), cold sores break and ooze out pus, leaving white crusts all over the mouth. While it takes two to four weeks for the sores to heal on their own, the good news is that there are some home remedies you can try to get rid of those cold sores faster. Unsightly and painful, cold sores are transmitted through close contact with an infected person through kissing or oral sex. After contracting the infection, people may develop cold sores within a few days with accompanying symptoms such as fever, fever blisters, and a headache. Consulting a doctor is the best solution as they may recommend antiviral medications along with some natural remedies you can try at home to get rid of the sores quicker. In this article, we explore a few natural remedies you can use to alleviate and prevent the recurrence of cold sores.

Medical Treatments For Cold Sores

If your cold sore is extremely painful, your doctor might prescribe antiviral oral medication to speed up the healing. Consult a healthcare provider to see which of the following treatments might work for you.

This herbal cream is as effective as topical Acyclovir cream for treating cold sores (35).

protip_icon Trivia
Rhubarb was used as a popular medicinal herb by ancient Chineses about 5,000 years ago.

The signs and symptoms of cold sores are as follows.

Signs And Symptoms

  • A tingling, itching, or burning sensation on the skin before the appearance of the sores.
  • Small fluid-filled blisters.
  • Merging of blisters, followed by their bursting and oozing that will eventually crust over. They may also crust over without breaking.

Usually, during the first outbreak, individuals may experience other symptoms like:

  • Fever
  • Ulcerated and/or painful gums
  • A sore throat
  • Headache
  • Muscle aches
  • Swelling of the lymph nodes

Children under 5 years can also develop cold sores inside their mouths or nostrils.

Many factors can play a significant role in triggering cold sores. The following section lists the causes and risk factors.

Causes And Risk Factors

The main causes of cold sores are some strains of the herpes simplex virus (HSV). HSV-1 is commonly associated with the onset of cold sores, while HSV-2 causes genital herpes. Both can cause sores in the facial area as well as the genitals.

As per WHO’s estimates from 2016, an estimated 3.7 billion 67% of the global population or people under the age of 50 have HSV-1 infection (Herpes Simplex Virus-1). On the other hand, 491 million people aged 15-49 or 13% of the global population have HSV-2 (Herpes Simplex Virus-2).

Once you have had an episode of the herpes infection, the virus continues to remain dormant in your nerve cells (in your skin) and can recur in the same place over and over due to improper stress management.

Some common factors that can trigger a recurrence include:

  • Fever
  • Viral infection
  • Hormonal imbalance
  • Fatigue and stress
  • Direct exposure to the sun and wind
  • A weak immune system
  • Hot and ice cold plunges

Factors that may increase your risk of developing cold sores are:

  • Burns
  • Medical conditions like eczema
  • Treatments like chemotherapy
  • Anti-rejection drugs (given during organ transplants)
  • Dental work that irritates the lips
  • Cosmetic procedures – laser peels, injections near the lips

These factors can increase your risk of developing cold sores, especially after a previous outbreak.

Although cold sores can heal on their own, they may take up to four weeks to go away completely. Here are some first aid tips to aid faster recovery.

How To Prevent Cold Sores

  • If you have been prescribed antiviral medications (ointments), use them regularly.
  • Apply sunblock daily.
  • Avoid direct skin-to-skin contact with people who have cold sores.
  • Avoid sharing utensils and lip products, towels, lip balms, etc., with the affected individual.
  • Wash your hands frequently and do not pick or pop the sore.
  • Manage your stress levels.
  • Do not have oral sex. Wait until the blisters heal.
  • Change your toothbrush if you develop a cold sore as it could harbor germs and may even spread the virus. It is better to get a new toothbrush once the sore has healed.

Note: Cold sores must not be left untreated for too long. If left unattended, they could lead to the following complications.

The virus that triggers cold sores can also cause issues in the other parts of the body in a few individuals:

  • Both HSV-1 and HSV-2 can spread from around the mouth to the fingertips. This kind of infection is referred to as herpes willow. It is especially common in children who suck their thumbs.
  • The virus can also cause an eye infection. Repeated herpes eye infections can cause scarring or injury, leading to vision problems and blindness.
  • Individuals with eczema are at an increased risk of the cold sores spreading all over their bodies. This is very rare but can lead to a medical emergency.
  • The virus can also affect the spinal cord and brain in those with a compromised immune system.

Should you pop a cold sore?

Dr. Michael says, “It is not recommended to pop a cold sore as this can cause inflammation and even infection.”

Does rubbing alcohol help cold sores?

According to Dr. Michael, “Rubbing alcohol is not an effective treatment for cold sores, but some topical ointments may help accelerate healing.”

How do you make cold sores go away in 24 hours?

Cold sores do not go away in 24 hours, but the itching, and pain associated with them can be relatively lessened by using home remedies or antiviral medications, including topical antiviral creams. These can also speed up the recovery process and help heal the sores fast.
