Cold sores go through several stages, and generally last anywhere from one to three weeks. The first symptom you notice will probably be a tingling or itching sensation on your lips, chin, nose, or cheek. This is a sign that a cold sore is forming. This stage lasts one or two days, after which a blister or cluster of blisters will form. About a day later, the blister will weep, or ooze; this typically lasts about a day. Afterwards, the blister will scab over and slowly heal.
