Set out below are self-help suggestions and useful information relating to conditions connected with cold sores. However, if you have any concerns that last for more than a few days, they should be reported to your doctor.

Cold Sores

Cold sores (Herpes labialis) are blisters on or around the lips caused by a viral infection. The Herpes Simplex virus which gives rise to the sores is dormant until stimulated by a variety of causes ranging from sunburn and chapped skin to allergies and anxiety.

The blisters appear after a brief period of itching and burning, last for a few days, burst and then form a hard crust that usually takes a week or so to heal.

Keeping the blisters dry will speed healing. Early application of some kind of drying lotion – alcohol, camphor, surgical spirit or a specific over the counter cold sore preparation – can prevent the blisters from erupting and reduce the healing period further.

Don’t squeeze the blisters – you may spread the infection. Wash your hands regularly and keep your towel separate. The condition can recur. See your doctor if it does frequently, is severe, or if you get an eruption near the eye.

It can be serious in some infants and adults with atopic dermatitis.
