Get Relief from Cold Sores: Symptoms, Causes, and Treatment Options.
What is a Cold Sore?
Symptoms of Cold Sore
- Tingling, itching, or burning sensations on or around the lips: This is often the first sign that a cold sore is forming and is known as the prodrome stage.
- Small red bumps: These will develop into fluid-filled blisters.
What Triggers a Cold Sore?Cold sore triggers can include stress, fatigue, sun exposure, and hormonal changes. The virus can also be reactivated by certain foods and beverages, such as chocolate and caffeine. When the virus is reactivated, it travels to the surface of the skin and begins to reproduce, causing a cold sore to form. This process typically takes 1-2 days. The following are the stages of a cold sore:
- The beginning stage of a cold sore, or early stage, is known as the prodrome. During this stage, a person may experience tingling, itching, or burning sensations on or around the lips.
- The next stage is the outbreak stage, where small red bumps appear and develop into fluid-filled blisters.
- The third stage is the crusting stage, where the blisters will dry out, crust over, and scab.
What Causes Cold Sore?
Once the virus enters the body, it remains dormant (inactive) in nerve cells. Several factors can cause the virus to be reactivated, including:
- Stress: Stress can weaken the immune system, making it more vulnerable to outbreaks.
- Sun exposure: Exposure to the sun can cause a cold sore outbreak, especially if the skin is already damaged or sunburned.
- Hormonal changes: Some people may experience cold sore outbreaks during certain times of the month, such as menstruation, due to hormonal changes in the body.
It’s important to note that cold sores can vary from person to person, and it’s not always possible to identify the specific cause of a cold sore outbreak. Some people may be more susceptible to outbreaks due to genetics or an underlying medical condition.
How to Diagnose Cold Sore?
The diagnosis of cold sores typically begins with a physical examination. A dermatologist will examine the affected area and look for the characteristic symptoms of cold sores, such as small red bumps, fluid-filled blisters, crusting, and scabbing. The dermatologist may also ask about the patient’s medical history, including past outbreaks and any known triggers, like sun exposure or stress. If you need and have any problem you can take an online dermatologist consultation.
If there is any doubt about the diagnosis, a swab of the blister fluid can be taken and tested for herpes simplex virus confirmation. It’s worth noting that other conditions such as canker sores and impetigo can also present with similar symptoms.
Cold Sore Treatment
- Apply a lip balm or cream that contains sunscreen to protect your lips from the sun, which can trigger cold sore outbreaks.
- Apply a cream or ointment that contains a local anesthetic to help numb the area and reduce pain.
- Apply a cream or ointment that contains the amino acid lysine, which can help reduce the frequency and duration of cold sore outbreaks.

Cold Sore Complications
- Eye infection: The herpes simplex virus can spread to the eyes and cause eye infections such as keratitis, which can lead to scarring of the cornea and vision loss.
- Encephalitis: In rare cases, the herpes simplex virus can spread to the brain and cause encephalitis, an inflammation of the brain. This can lead to seizures, confusion, and even death.
Cold Sore Prevention
- Practice good hygiene: It’s important to keep your hands clean and avoid touching your face, particularly around the mouth and nose, as the virus can be spread through contact with infected fluids.
- Avoid sharing personal items: Avoid sharing personal items such as towels, lip balm, and lipstick, as the virus can be spread through contact with these items.
- Use a lip balm with sunscreen: Using a lip balm or lip cream that contains sunscreen can help protect your lips from the sun, which can trigger cold sore outbreaks.
When Should I Call the Doctor?
- Eye irritation: If you experience eye irritation, redness, or discharge in or around your eye, it’s important to see a doctor right away. Cold sores can spread to the eyes and cause eye infections such as keratitis, which can lead to scarring of the cornea and vision loss.
- Weakened immune system: If you have a weakened immune system, you may be at a higher risk of developing complications from cold sores. People with HIV/AIDS, cancer, or those taking immunosuppressive drugs should see a doctor if they develop a cold sore.
- Swollen cold sore: If your cold sore is swollen, extremely painful, or infected, you should see a doctor. A swollen cold sore could be a sign of a secondary infection, which will require antibiotic treatment.
