About cold sores

Medically reviewed by Dr. Ammar AL-ANI, MBChB, CCBST, AMC
When to consult a doctor for cold sores?
Most cold sores heal on their own within 7–10 days, but there are situations where seeing a doctor is recommended. You should consult a doctor if:
- It’s your first cold sore outbreak and you’re unsure of the symptoms.
- Cold sores occur frequently or are unusually large and painful.
- Sores last longer than 10–14 days without healing.
- You develop a high fever, swollen glands, or signs of a secondary infection (like pus or increasing redness).
- The cold sore appears near your eyes; this can lead to serious complications.
- You have a weakened immune system due to illness or medication.
- The cold sores significantly affect your ability to eat, drink, or speak.
What are the causes for cold sores?
Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which is highly contagious and spreads through close personal contact. Here are some common cold sore triggers:
- Stress and emotional strain
- Fatigue or physical exhaustion
- Illnesses like colds, flu, or fever
- Exposure to strong sunlight or UV rays
- Hormonal changes (including menstruation)
- Weakened immune system
- Injuries to the lips or mouth
- Dehydration or dry, chapped lips
How do you identify cold sore symptoms?
Cold sores have recognisable signs and symptoms, typically appearing around the lips or mouth. Common symptoms include:
- Tingling, itching and burning sensation
- Small fluid filled blisters
- Blisters that burst and crust over
- Scabbing and healing
- Swollen lymph nodes, mild fever or sore throat
How to prevent cold sores?
Here are some tips to prevent cold sores:
- Avoid direct contact with cold sores, no kissing, sharing utensils, or lip balms with someone who has an active sore.
- Manage stress levels with mindfulness, exercise, or relaxation techniques.
- Use lip balm with SPF to protect your lips from sun exposure, a common trigger.
- Keep your immune system strong with regular sleep, a balanced diet, and hydration.
- Avoid excessive fatigue and physical exhaustion.
- Recognise early warning signs like tingling and start antiviral treatment promptly.
- Stay well-hydrated and avoid letting your lips dry out.
Complications of cold sores
Cold sores are usually mild and self-limiting, in some cases they can lead to complications, especially in vulnerable groups. Here’s a clear breakdown:
- Secondary bacterial infections: Blisters can become infected, causing redness, pus, or increased pain.
- Eye infections (Herpes keratitis): If the virus spreads to the eyes, it can lead to serious issues like corneal damage or vision problems.
- Severe outbreaks in people with weakened immune systems: Such as those with HIV, cancer, or on immunosuppressant medications.
- Eczema herpeticum: A rare but serious condition where the virus spreads to large areas of skin in people with eczema.
- Psychological distress: Recurrent cold sores can cause anxiety, embarrassment, and social discomfort.
- Scarring: Rare but can happen if sores are repeatedly picked at or become infected.

What can I do to avoid spreading cold sores to others?
Preventing the spread of cold sores is important since they’re highly contagious, especially when blisters are present. Here’s how you can protect others:
- Avoid kissing, oral sex, and close facial contact while you have an active sore.
- Don’t share personal items like lip balms, cutlery, drink bottles, towels, or makeup.
- Wash your hands frequently, especially after touching your face or applying cold sore treatments.
- Avoid touching the sore, and if you do, wash your hands immediately.
- Use a separate towel or pillowcase while you have an active outbreak.
- Stay home from work or social events if your job involves close contact with others, particularly babies, elderly people, or immunocompromised individuals.
- Avoid triggers like stress, sun exposure, and fatigue to reduce recurrence risk.
