Cold Sore Treatment: Fast Relief & Healing - Causes & Remedies

A cold sore is a blister that typically develops on the mouth. Also called a fever blister, the cold sore is caused by the herpes virus. The cold sore starts as a small, raised bump on the lip and may cause a slight tingling sensation. The cold sore then develops into a blister and can be both unsightly and painful. A cold sore will normally last for about a week to 10 days. To cure cold sores quickly or to minimize the episode, a sufferer must be aware that one is forming.
