Blisters under my nose - Cold Sores

Dear Ask The Doctor: I have had a reallybad cold and now I have a rash with little pussy blisters under my nose. Can you tell me what this is and what I need to take to make them better?

Dear Sandy: What you could be having are cold sores caused by herpes simplex type 1 virus. Cold sores most commonly appear on your lips. Occasionally, they occur on your nostrils, chin or fingers. There is no sure cure. Valtrex and Abreva will help you control the symptoms and heal faster. Take care.
