Cold sore healing can also be improved with hydrocolloid dressings (Compeed invisible cold sore patches) available in most pharmacies. Local anaesthetic creams applied to the blisters and oral painkillers such as paracetamol can ease any discomfort of the blisters.
Without treatment, cold sores usually heal within 7 - 10 days.
If you want to discuss your cold sores with a doctor, you can book a telephone consultation. Our doctors will be able to offer personalised advice.
