General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
If you are unsure about a lesion, a flare is more severe, a sore spreads or has not healed after ten days, or recurrences are frequent, see a doctor in the coming days.
Record how often cold sores recur and the circumstances: fatigue, another viral infection or exposure to cold can contribute to a flare. These observations help prepare the discussion.
During a flare, the virus spreads through direct contact with lesions and saliva. Avoid kissing those around you, especially young children, and contact with people whose immune defences are weakened.
Do not scratch a cold sore. Wash your hands after touching it and do not rub your eyes afterwards. Use your own towels and do not share lip balms or lipsticks.
Always ask the pharmacist for advice before starting self-treatment, even if flares are familiar. Present the care products or medicines you have already used.
See a doctor the same day if a cold sore comes with a high fever or intense pain, a red or painful eye, or sensitivity to light. Same-day medical assessment is also necessary if your immune defences are weakened.
