About cold sores
Cold sores are small, painful blisters around the lips or mouth, usually caused by herpes simplex virus type 1 (HSV-1). They typically heal in 7–10 days. Triggers include stress, illness, sun exposure, and tiredness.
Early treatment with antivirals — ideally at the tingling stage — may shorten duration for some people. Over-the-counter creams are also available from pharmacies.
How a telehealth GP can help
A NewDoc GP can review your symptoms, prescribe antivirals if clinically appropriate, and advise on prevention strategies. Recurrent or severe outbreaks may warrant further assessment.
